    Hello ,I would like to request some advice on a predicament I am in.
    I have been running devolpment builds of crafbukkit and a number of plugins ,which I did at my own risk ,and came to find a working dev build of the plugin "Multiverse Core" (v2.4-b512). The Plguin has overwritten all the worlds apart from our main world. I think this may be because it was trying to convert them ,but I am not sure. This is exactly what happened:

    I would love to know if there is a way to get tese worlds back. I have backups ,but some of the worlds are new ,and I run a private server , so I don't have backups for all the world. I am using windows 7 ,is there a way to bring back the worlds plugin or otherwise (,if you need I can post my plugin list)? Thank you for your help.


    P.S. I am aware this may be in the wrong place ,as you can see this is my first post , my apologies.

    Bump ,This is quite big issue for the server.

    Holly sh***, that's quite serious :(
    If the files were overwritten, there's no possibility to "regenerate" the old data without a backup.

    If the files were deleted, they could have been "recovered/undeleted" but on overwriting them, you'll not be able to get them back.

    Well if you update "hot" and don't have full backups, tough luck.
    Also, I very much doubt MultiVerse would actually overwrite existing worlds.

    I had the same problem on my server, but since I've made a backup before, I was able then to fix this issue.
    The thing is: once you download CB1.2 and Multiverse Core, BEFORE running the server, download the AnvilConverter from mojang (http://assets.minecraft.net/12w07a/Minecraft.AnvilConverter.zip), put it into your server directory, and run the following script:

    Code:
    set serverpath="C:\MinecraftServer"
    java -jar AnvilConverter.jar %serverpath% pixelworld
    java -jar AnvilConverter.jar %serverpath% sygma
    java -jar AnvilConverter.jar %serverpath% sygma_nether
    java -jar AnvilConverter.jar %serverpath% sygma_the_end
    pause
    
    Then, CraftBukkit won't create maps, since the maps are already converted.

    At the office, but since you posted "I did this at my own risk" I'll forgive you and give you a hint. Bukkit did not overwrite your worlds, Just your level.dat. This should be ok.

    Before you do ANY of this. Make a backup. Don't learn a lesson twice.

    Using an NBT Editor open the current level.dat and change the VERSION to one less than it is. I don't remember the value now, but I can find it later tonight. Then make sure your bukkit server is 2032+, as this error was (as most arn't :() not caused by multiverse, but by a bukkit error which was patched and accepted in 2032+. Then let your server come up again. All worlds should get converted properly.

    Hope that helps,

    Thanks you for you help ,I certainly appreciate it.
    If it means anything, more than the level.dat was changed; The players folder was also cleared. I will wait until I get a definite answer on the version number.

    Amazing that the best "customer" support I have ever received is from a free gaming software. Fantastic work guys.

    Do you have the VERSION code yet? I've been trying to find out more about the world format but just gave up.. I'm too busy.

    Sorry guys. Got late last night.

    You'll want to change version to 19132 (It will have been set to 19133 by the convert bug).

    /cc Cody Pawlowski Miroku

    For reference, the backup function was failing. This has been fixed in CB 3023 (Before everyone freaks out: "What no backups whaaaaaa?!?!" You knew when you installed a dev build that you threw everything out the window.). I've tested and the backups work properly now.

    Here is an example conversion from one of my worlds:

    1.1 level.dat

    1.2 level.dat

    Hope this helps.

    Got a similar problem, except for me its just the regular world I think.
    Tried to reconvert it, but something is not right as it takes 2-3 sec instead of several minutes to reconvert.
    So my map works and everything, but it reverted itself to a 6 days old map (First time I tried Dev build bukkit).

    Its frustrating as I got about 15 active players, and 6 days of building gone is just to much.

    Edit: So I followed the tips in this post, and after updating Multiverse I managed to fix my nether world. But my Normal world is still a week old. So Im guessing its possible to fix that aswell, but I do not know how :p. Anyone able to help me out?

    I'm sorry to bring this thread back ,but I'm in need of some help. What are the exact steps I need to follow? Even if it is some finalization that the worlds are gone I would be happy so this thread can be closed. Thanks you and sorry for being blind to your help.
