I encountered an error when swapping from one computer to another.

Error wile running event
playtime-plus::on_player_display__resolution_changed (ID98)
playtime-plus/control.lua:55: attempt to index field '?' (a nil value)
stack traceback:
playtime-plus/control.lua:118 : in function
<playtime-plus__/control.lua:116>

Thanks for the report.
I couldn't reproduce the bug but added a workaround to prevent the crash.
Also I updated GUI repositioning algorithm for screen resizing.

If the problem keeps occurring, please let me know.
