    I googled it and one of my Admins looked around too, we have found literally only 1 other instance this happened with someone and no one responded to him.

    The Problem:
    My signs in the game are randomly getting erased. It looks like it might be chunk based, and there is no single type of sign that gets erased. Normal signs, protection signs, redstone circuit signs... anything is possible. I've personally only had regular signs with just words erased, some players lost the redstone signs... 1 player had his private signs for lockette erased. I've searched for anyone having anything similar but haven't returned anything yet.

    And forgot to add, Chests in that same chunk are empty after also.

    Ok so plugins we have in common are:

    LWC
    Multiverse
    MyHome
    MyWarp
    Pailstone
    Permissions
    WorldEdit

    So we need to find others who have some of these in common if we can narrow it down maybe we can find out what's happening.

    Out of these plugins which versions are you running ?

    Here are some posts I've copied from the Pailstone Thread with some refering to it

    neither have LWC so it's off​
    multiverse isn't on the 2nd one​
    MyHome and MyWarp aren't on 2nd also...​
    World edit in't on #2...​



    The 2 common plugins are Pailstone and Permissions but we should wait to see if someone that doesn't have either one or just 1 of them to narrow it further.

    Hey, PailStone dev here. PailStone doesn't interact with inventories, so the fact that chests are affected as well means this bug isn't in the pailstone code. I have a feeling that it isn't in the permissions code either, but I don't know for sure. I would suggest that the bug is either in bukkit's or notch's code.

    i'm getting this issue on signs aswell as chests, I don't use PailStone.

    permissions is the only common plugin i'm seeing but I don't see how that is going to erase signs and chest inventory. it must be a bukkit/minecraft bug

    I have this issue on my server as well. I don't have PailStone. The event happened on my server...luckily I had a backup of map. I reverted to the backup and it happened again, this time with Minecart Mania errors. I removed Minecart Mania and I have not had this bug happen since. 1 day and counting.

    Seeing the same thing, already going crazy, as it only affects some chunks and not others.

    Chests as well as signs get wiped from one moment to the other. Only ever since 1.7+

    In the PreciousStones thread of @phaed some people mentioned it being a combination of CraftBook/Falsebook with PreciousStones, but since I removed PS it still happens. I havent yet tried removing any other plugins.

    Also seeing how everyone else has different plugins and this still happening, I get the feeling tht it's Bukkit/Notchcode problems?

    same here. also it seems that once it happens in a chunk, it keeps happening in that chunk.

    I posted the bug here http://leaky.bukkit.org/issues/1052
    not sure how it works but it looks like people need to upvote them to get them noticed?
    so do that!

    Upvoted! Also as a side note I do not believe it is related to a NPE in in the new furnace events, as I checked logs and did not see that anywhere, yet we have had this same issue.

    CraftBukkit #952 don't erase signs and don't delete chests. I keep this version because all my chests have been erased... and all my ressources too :/

    This issue has definitely been made known to us previous to this thread, I guess all I can say for now is to keep an eye on the issue which @Ratchet posted. However please don't vote spam it :) the sooner that vote plugin gets disabled the better.

    If you have any new or more information regarding the matter then the best place to put it would be in a reply to the issue on redmine.

    not sure what more info I can give, what would you like?

    just had another player have 10 of their chests wiped clean today, all the signs in the area are wiped clear too..

    I've been able to recreate the erasing 4 times today, controlled testing, so hopefully we'll get this figured out :)

    This is actually a problem with the base minecraft code. My mate and I work on AdventureCraft, (a single player mod) and our users were having a similar issue. There is a bug with chunks atm, it appears. It seems it has to do with the new code added for pistons. When chunks are unloading, it marks the tile entities as having been deleted. The world, as it iterates over them, sees that they have been deleted, and then reloads the chunk, and deletes the tile entities, resulting in the signs/chest/and whatever other tile entities being reset.

    The bug may be in the provide chunk code, but the easy fix is to add an extra flag to the tile entities that have been marked deleted. Before check to delete, just have it not.


    Technical details to come (may also include a fix), but unfortunately we are both stuck driving to his brother's wedding. (we were supposed to leave last night, but fixing this exact issue delayed us till 4 am). So basically, yeah. Not a plugin issue. Maybe CB devs will pick up on this and provide a fix before we do ;D *hint hint*

    I know, I've had a couple users on my SMP server suffer because of this as well. The chest wipes are bringing about quite a bit of sadness, especially since we have a policy of not restoring items. =(

    Its rather unfortunate, but with us on the road/doing this wedding, dunno if we'll get a fix out soon. I msg'd @EvilSeph on IRC, so maybe he can pick it up after some talk with Cryect when he [dude I'm driving with] can provide more attention span.

    Atm radio singing takes over in importance ;D And you know, driving.

    Same thing happened to me...It happened twice after i did a rollback with BigBrother...I thought it messed up.


    So now what...Go back to 952 and have the danger of pistons never work again ?
    Do you guys think this will be fixed in the next update that should be come out soon?

    Odjit

    @Sandbird The bug is in 1.7 So unless you retrograde all the way to the last 1.6.6 RB for CB, you won't be rid of it. However, are you sure your problem is as listed here? Is it a chunk issue, or are you just talking about BB rollingback signs and chests with no contents? Cause that would be different.
     
  25. Offline

    Sandbird

    Yeah thats what i thought also until today, that BB did this...But i just talked with a player right now saying that his chests are empty and how is it possible since he LWC them, and also the signs above them were empty too.
    Since i haven't rolled back anything for 3 days now, it all made sense that this isnt BB and its this thing we are talking about.

    Last time this happened was about about 500 clicks from the location it happened now so its gotta be a chunk error thing...since i only do radius rollbacks when necessary.

    2 more of my players lost all their stuff.....I advise them to use VirtualChest plugin that doesnt "hang" from the map files.

    Good find and a nice read, I've passed it on to those with more knowledge on Tile Entities than me.
