I've recently been experiencing a very similar problem. Have you tried downgrading MyWorlds to the previous version you had before ? Perhaps some of the mods that you didn't update are not compatible with the newer version for whatever reason.

 

Yes please help :/

Send me the entire startup
and crash log.

 

Could be BKCommonLib or any plugin by bergekiller.

 

PyPKjE Your issue is a plugin being outdated. Probably BKCommonLib.
As for the OP, have you tried upgrading all your plugins?
When did this start occurring?

 

we already fixed it.. We downgraded BKCL and all plugins by that author to one version down and everything works fine now...

 

So please mark the thread as Solved.
