Cheater abusing the system

that is always present on screen

See Jellby's post above. Has it always been the case that the undo button was there when you weren't the active player, or have you noticed that this is a new behavior since, say, 19 Nov. or so?

I'm surprised that something this big would only have been recently discovered with the game being out so long. Did it really go unnoticed that long, or did something in the framework change recently that introduced it?

It could be related to these:

In which case it looks more like a BGA-wide change, that is either buggy or exposes bugs in games that had been "hidden" so far.

This seems huge. So is the hypothesis that this change is somehow now causing "undo" to display to all players and not just the active player (at least in Patchwork)?

I communicate regularly with the developer. (She and I collaborate on Terraforming Mars. )

I informed her of the bug, and she has implemented a fix.

If anyone experiences a recurrence of this bug, please post here or message me and I'll let her know.
