When going to create a world and clicking onto the preview tab the game crashes. I have a pretty big mod list so if needed I can slowly go through them all and see if another mod is causing the crash, but heres the log for now:

latest.log

Looks like the incompatible mod is WorldEdit. Could you please confirm if this is the case? If there is another crash without WorldEdit, please attatch the new log file again.

Could you please check if this fixes the issue:

world_preview_1.0.1.tar.gz
