Mantis doesn't want to work for me right now, though the weather here is pretty bad and my net has been screwing up as of late. If someone wants to submit this to Mantis to get the bug fixed, feel free.
Anyways, if you try to teleport using a gate without entering it when the gate is not next to a solid body (platform, box, ground, etc.) it will never allow you to teleport. Instead, it will tell you that it is loading the chunk while you float to the bottom in the background - unable to control your character. After a few seconds, you regain control of your character since it is unable to load the area you selected. You must place a platform so that you are standing directly next to the gate before you are able to teleport to the selected area - or just jump inside.
Now, this wouldn't be a big deal except I tried to jump past a gate to teleport away from my imminent death only to watch my character float to the ground covered in mini-whales while the game tried to load the area I chose. Needless to say, I died while waiting for the chunk to load. Very frustrating.
