using factorio 0.16.28 and attach notes 0.1.7, i just got
error while running event attach-notes::on_gui_opened (ID 83)
attach-notes/scripts/entity-notes/controller.lua:81:
attempt to index local 'opened' (a nil value)
tested again: the error seems to always pop up when i click on a SwitchButton (from the mod with the same name). I don't know whether that mod or this mod causes the problem, but this mod shouldn't crash in any case.
ps: this mod is really nice for documentation of blueprints and complicated circuitry, but while playing and editing circuitry or normal setups i don't like to always get the window to edit notes all the time. is there some option to never get it automatically but only when clicking some button or pushing some hotkey ?
