Please post the debug.log found in the logs folder of your game directory.

It may be quite large, so if it will fit here, please use spoiler tags.

You may have to post it on an external site and link it here depending on the size.

 

debug.log has much more information in it than a crashlog.

Spoiler

debug.log

 

Unfortunately I am not sure what is causing that error.

Perhaps try removing mods 1 at a time since you only have a few, and see if it works.

I would start with Extended Caves, only because in the log it mentions jigsaw features, which I would think would be used making caves.

If it still crashes, maybe lycanite mobs since it has about 8 million other non-fatal exceptions in the log.

 

Perhaps someone else will see this thread and have a more informed answer for you.

Sorry I couldn't be more help!

Thank for the help! I will try this
