[Aesop]

Pathing is easily exploitable in Guk, the pathing is so messed up they literally walk back and forth in the water (reference Lovely's screenshot of the water in front of EE).
I witnessed some people using the exploit on the spiders (in the waterways near giant heart spider), then experienced it myself after I fell off the walkway on the way to zone with a train hot on my heels. I tabbed out thinking I was fucked, and after a minute or so I tab back in - almost out of air with the entire train running back and forth on top of the water.

Naturally no one noticed it in BETA.
