I'm getting the following error any time a modded weapon fires in a mission:
___________________________________________
############################################################################################
ERROR in
action number 1
of Step Event0
for object obj_ally:

index out of bounds request 12 maximum size is 12############################################################################################
gml_Script_sc_create_ally_bullet (line 166)

gml_Script_lua_state_exec (line 21)
gml_Script_lua_call (line 8)
gml_Object_obj_ally_Step_0 (line 26)

This seems to be an error in the game logic, preventing any modded weapons from working. I don't have the experience needed to modify the GML files and fix this problem. Any advice?
