So in multiplayer a buddy and I are experiencing desyncs with the latest version of Picker Extended playing on our headless server. If you have the mod option for orphan finder enabled (on by default) if you have an orphan on screen, it will be highlighted by Picker and then you will immediately desync from the server. Turning the option off fixes the problem. Orphan finder has no issues in single player.

Also, desyncs when dying in MP, with accompanying error.

orphans.lua: 18: attempt to index field 'cursor_stack' (a nil value)

The desync is probably related to a Factorio bug fixed in the next version of Factorio. Let me know if they persist at that time.

The script error (not a desync) should be fixed in the next version of picker. I added some additional sanity check around the stuff using cursor_stacks

Thank you both for the reports.
