Explication of the bug: When in a club world, if you use the CTRL + A (Atlast) Click to the world you want to go to, and press [E]. You might crash.

Step to reproduce:
- Join a club world
- Change Class (Optional, still can happen without doing so, but it's more rare)
- Open Atlast ( CTRL + A )
- Select the world to go to
- Press [E] instead of pressing the button "Enter"
- ( Bad luck that you crash is pretty high )
This issue as begin to occur since the Crystal Update, not after a Update's patch
