Clocktower bug
The Clock Tower is not lag friendly (as with certain Super Adventure Box levels), especially if you have a spotty Internet connection. Sometimes the server may not catch your character’s successful jump (even if you actually did on your side), and will teleport you back.
Despite my high latency I’ve never lagged to a noticeable extent, and I’ve seen others with the same problem.
My latency/ping/ms/whatever you want to call it is usually stable at 220. Sucks to be in New Zealand but there is nothing I can do about it if lag really is the case.
