Yeah, this map is just no.

Yea, my friends and i just experianced the key despawning. And then he glitched, somehow through up to the ceiling and died on the spikes. Can they key at least respawn?

Having only one key can lead to odd glitches and just means the fastest grab via latency gets to be as slow as they want
put a door with crates behind it if you wanna slow down the really fast runners
