TRADE MINECRAFT 2014 V2 exploit/bug/whatever, players teleporting on the roof

inb4 TF2 update, again, also this person glitched it, for no particular reason, Dr. Chipolte managed to build an exit teleporter on the roof and players started TP'ing up there.

Also, the reason the trades weren't working, Valve put out another subsequent update to TF2 fixing crashing related to using custom HUDs.  I couldn't even change loadout on my Scout for some dumb reason and steam tells me "no connection" when clearly it ignores all other internet activity going around it.

That spot is more of like.. A feature.

As long as it doesn't allow players to get into enemy spawns I don't mind it that much.
