Hi! I seem to have the same bug in 1.2, although with slightly different parameters:
___________________________________________
############################################################################################
ERROR in
action number 1
of Draw Event
for object oGame:
Variable Index [11] out of range [11]
at gml_Script_menu_draw
############################################################################################
gml_Script_menu_draw (line -1)
gml_Object_oGame_Draw_64
As RetroCables said, it happened once I collected the 11th gear and tried to change palette through the options. If it makes any difference I started playing in 1.1 and got half the gears there, then updated to 1.2 and collected the rest there.
And thanks again for the awesome game!
