Sometimes when last user disconnects (maybe while turn is changing?), server crashes #29

Undefined variable error from line 300 (in the getTurnData() method) when trying to access the name of a player who just disconnected.

This bug seems like it might be hard to replicate, but my best guess is that it's a timing issue with the turnChange and disconnect events.

Idea for a solution: Just add another check to the offending function so that it only runs if the variable it's accessing is not null.
