Bug when switching team to spectators

[Terra]

Spoiler

I came across this weird bug where if you switch to any team in CTF (untested in other gamemodes) and respawn, then switch back to spectators, a message will say "[PLAYER] fell into a bottomless pit," followed by the usual message of switching to spectators, as you then fly up indefinitely until you respawn.
EDIT: Whoops, I just realized I accidentally posted this in the wrong place.
