//Changelog A5
//Added low gravity during wall building phase for red team, to help non-jumper classes get atop
//Fixed buildings not being able to be built after wave
//Fixed upgrade room not working
//Fixed Gatebot trap stunning giants
//Fixed some traps not properly reducing the tower credits and breaking the system
//Walls can now be resold during the wall phase, also fixed an error relating to the nav (I couldn't make the buttons melee-only, but I did make it so your not going to buy walls by mistake when the wave is over)
//Removed Engie hints off each wall, no more stuck engies
//The wave now pauses bot spawning shortly after it starts, so spies and shit won't harrass players, but to allow important bots like the time's up to spawn
//Moved the Tower Credits on the HUD to the far left so it isn't blocked by the sweer "X killed BLUE ROBOT" spam
//Ghost trap now properly animates and doesn't stun giants
//walls have been altered a little to make the nav work
//Changed the towers a bit, to make the nav work
