PATCH THOSE EXPLOITS I FOUND (With help of other players)

[Raviolo]

You can actually put a TP in the spawn of 2014 event map (Doomsday Reskin). Spy can Teleport in and kill, or just for fun. You can put TP behinfìd the glass door, for griefing/trolling. Teleporter on the Hammer Button will be indistructible... In mini games you can actually accelerate before the start of the round (the fence will move with you too). You can stand on top of the spawn door to block it! (Toasty).
Hope this will help you. And sorry for my bad English.

another exploit to add to this list: you can stand ontop of the spawn door to block the exit off completely
