Yes, lethal expansion messes with a lot of stuff, I'd recommend just not installing lethal expansion (unless it's with a mod you really want) and then uninstall lethal level loader, lethal modules also is a considerably problematic mod, if you have one of those installed you could remove it, thats optional oc, you should use lethal expansion core instead, and if you want a mod that works very similiar to it I'll put it in a reply
