Issue: Map Geometry won't spawn/be visible during Custom Games

I’ve come across an issue where I save a map in Forge and everything’s fine, but when I load that same map in CG, either the map geometry won’t spawn or it will but remain invisible. From some testing, I see that adding bots to the match causes the glitch to occur, but removing them afterwards doesn’t fix it, only restarting the game fixes it. But since I want to playtest my maps with bots, I’m kind of in a pickle here.
