besides the crashes I haven't had any really big problems with doomedit
my only real problem stemmed from doomedit not updating the naming scheme of my light ents, because i accidently changed a berserker powerup to a lightent
thus it had the light ent naming scheme on the berserker powerup as well as any new lights i made
must be a bug for doomedit to not updating the naming scheme of the ent regardless of the mistake
