Stone disappearing from Chunks

The title pretty much says it. I've got a server which has been running the same world since something like 1.3, and all of a sudden, when I grabbed the dev build (I know, I know, it's a dev build, stuff like this can happen) for 1.1, I realized stone was disappearing. Not small amounts, but entire chunks of stone, from bedrock to sky, and JUST smooth stone... similar to //replace if using WorldEdit, but I know that's not it; it left all signs, torches, paintings, etc where it was, and Worldedit doesn't do that. Anyway, It's already caused irreparable damage to my map, but I'm still trying to figure out if it's a plugin, the build itself (1774), or some combination thereof. I don't even know if it's still happening. I know that's not a lot to go on, but I know the console isn't showing anything, so it's not some terrible error. Anyway, if anyone has any ideas, shoot - I'm game. ...and thanks!

 

Same problem here! Need help.

 

Do you mean Beta 1.3?
If you are running a world from Beta 1.3 all the way to the official release 1.1 then you sir need a new map!
Thousands of changes have been made from Beta 1.3 to now. In fact. I want to say millions of changes. You might just need a new map =/

 

Do you use OreObfuscator?

 

I did.

 

i did not, and it happened to me, maybe spout?

one case all stone in loaded chunks dissappeared, bedrock to surface

and now again, on stuff people build in the end, all vanished


not sure if its spout

does the TS happen to use craftproxy?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

This happens by using a Spout version thats not compatible with the CB version you use.

Only way to restore is by using a backup (as you always have backups if youre a good server owner) or restoring chunks with //regen

 

Thank you sir, I already did the second part (regenerated chunks), but had no clue about Spout causing this.
