Just some guesses: - I'm figuring floating NPCs and walking through solid surfaces might be from incorrect navmeshes. IE maybe they baked them, moved some stuff around, and forgot to rebake. Or forgot to mark some objects static, etc. - Meshes disappearing.. not sure, thinking maybe theyre using some fixed size arrays to avoid reallocations but maybe theyre hitting a fixed size limit and things get evicted. - Weird spawns. Guessing this might be something like a broken line of sight calculation. Maybe similar to the theorized navmesh thing -- occluders could be wrong too
