Its 169 Megabyte not gigabyte

OH MY GOD 169GB

Thanks for the effort, I'll test to see how it is.

@Sharp-Shark Hey, I've just added a navmesh, but after about 100 game crashes and still some glitching bots I don't really know if it works as you expect. I've never done anything like this before, and I think this map is not the best map for bots (because of the very tight spaces and lots of props on the floor). You can try it if you want, hope it just works a little for your purposes, if not, sorry, like I said, never made a navmesh before. ^^

No navmesh or ai nodes, right?
