Crash after "set map size"

[DamianX]

Steps to reproduce:

• Open any environment, create a new 100x100x1 map
• Select all tiles
• Set map size to 50x50x1
• Click anywhere inside the new map

P.S.: I encountered this on the release version but I got the call trace by running the game in intellij IDEA, due to #77
