Issue: After placing the tiles into the folder and loading up the map editor, everything works fine. The tiles show up, I can place them, everything works. As soon as I try to test the map, though, the game crashes and gives me this error:


___________________________________________
############################################################################################
ERROR in
action number 1
of Create Event
for object obj_controller:

Data structure with index does not exist.############################################################################################
gml_Object_obj_controller_Create_0 (line 40)


What can I do to resolve this?


UPDATE:
The problem occurs when I try to load ANY map. The game is unplayable.
