Something wrong with "The Sharp Unknown"

Describe the problem. Be as specific as possible!:

I literally cannot attempt to do anything in this map without my game closing itself. If I try to mine ores, kill monsters or leave the map the client lags, then dies. Doesn't happen with any other Aqua Road map.

Can't really take a picture of this

Compare minimap to the platforms you see. In Tespia some maps didn't match, and if you landed on something that was invisible to the minimap, you d/c'd.
