Ah, I suppose your script runs before GMLive’s initialization? You could make it
if (!live_enabled) enemies_struct();
in the script and add
if (live_enabled) enemies_struct();
to the end of obj_gmlive’s Create.
Or rename the “GMLive” script to “__GMLive” so that it runs before the rest. Kind of silly but that’s the world we live in starting with last year’s updates.
