Error while running event multiple-stop-names::on_gui_opened (ID 87)
__multiple-stop-names__/control.lua:17: attempt to index local 'gui' (a nil value)
stack traceback:
__multiple-stop-names__/control.lua:17: in function 'update_gui'
__multiple-stop-names__/control.lua:50: in function <__multiple-stop-names__/control.lua:43>
I think on_player_created is not a per-session event, so gui is never initialized for me.
