Server Crashes After I Log in

Actually, when i log in to the server it let me be in my world like 2 seconds and after that immediately the server crashes.

This is the log: https://mclo.gs/BZF3M9D

I have the mods that it looks in the screenshot :

Recently i try to solve the problem removing Mowzie´s mobs mod and happend that the log show. I think the main problem its the hardcoredungons mod, because the mod try to generate a structure/mob in a inapropiate zone (Something like that)

Today i try to rollback a few days and unistall all the dungons mods and it works, it seems like one of these mods cause a bad generation of any structure.

Thanks for your help
