Well ever updating anything make a back up. So by not backing up its your own fault.

I got a backup plugin and it corrupted everyones chests and inventories so i got rid of it. And then 2 days later this happened. I need help not people flaming me for not backing up my world

[The_New_Pro]

Im not flaming just telking a fact and the only help I have is to cheat it back in if you didn't back up.

Well do you at least have ANY idea why this would happen? Just by simply changing the Jar file to an updated one?

[The_New_Pro]

Yes changing the jar may sometimes have side affects so thats why you back up sorry if I seemed like a jerk before just backing up before you change the jar is easy to do so I just thought you where one of the stupid kids that come here too often. Anyway sorry you lost all the tekkit stuff.
