Whenever I startup my game, I get this error: Data structure with index does not exist. at gml_Script_load_game (line 21) - for (var a = 0; a < 36; a += 1 global.lc[a] = levelslist[? a]; That's funny, because in my save game code I have this: var levelslist = ds_list_create(); for (var a = 0; a < 36; a += 1 ds_list_add(levelslist,global.lc[a]); ds_map_add_list(mainmap,"Levels",levelslist); And I know for a fact that it saves properly. WHat's the problem? I'm not really experienced with JSON yet.
