[2.0.76] Multiplayer desync when using event.in_gui from CustomInputEvent

[heyqule]

What did you do?
When the host perform left_click actions. It causes clients to desync. (Mod: erm_unit_control 1.1.13)

What happened?
It looks like event.in_gui from https://lua-api.factorio.com/latest/eve ... InputEvent are out of sync for multiplayer. See screen shot.

What did you expect to happen instead? It might be obvious to you, but do it anyway!
It should not desync.

Does it happen always, once, or sometimes?
Always

Thanks for the report. Issue is now fixed for the next release.

Unfortunately there are no workarounds here, value of in_gui is simply unreliable up to 2.0.76 due to a bug.

Thank you. I didn't expected a fix on Easter Sunday lol.
