Alright so here's the story. I'm working on a jailbreak map(doesn't matter why). And as I was making an obstacle I tried to make a cogwheel looking structure and ended up crashing hammer after attempting to use the carve tool. The map was saved so no worries, however after compiling I noticed I spawned in the middle of the map, there was no lighting, and all entities were gone. I checked my vmf, and noticed that all brush entities where turned into nameless entities with oddly named values, and all regular entities have been removed completely. Is there a way to deal with this? And if so then how?
