I downloaded a copy of circle-3.5, and I wanted to somehow delete all the stock zones, mobs, objects, trigs, wld files and shops, without causing any errors in, like, spec_proc.c and spec_assign.c... I tried doing that, but after I did, I create a mob and object, and the thing just didn't disconnect me, but I couldn't really do anything. There wasn't a > anymore, and none of my commands registered.

By the way, I have a very limited knowledge of C..

Good news! I did it!
