This is likely because the mountain tile is not a tile type that you can move 
into, and a move command is likely being returned as null, and as a result 
there is a null object that should be surrounded by "if (varname != null).

I'll verify.

PS If this is the case, the expected behavior is to move to the closest valid 
tile.
