Reverting usually takes a bit (like, somewhere between seconds to minutes) to show up in the app, as far as I've experienced at least. It won't show in the app in any special way other than it would be the prior player's turn.

Kinda awkward in a great big war when the three major power fighting each other has to all take their turn again, but I guess it'll have to do :)

So, after the last couple of days' instability, several of the games I play in have encountered a bug where GMR will claim it's one players turn but the save loaded will be anothers, and in this particular case reverting doesn't seem to help.
What do i do?

Ah right, I've of course never played actual hotseat. I guess it's in the same category as the horrible "can edit then accept another player's trade offer" bug, which apparently has existed for years without being fixed.

I've played a lot of vanilla Civ multiplayer and never had it happen there. Of course, that's hardly proof of one thing or the other, but I'd at least recommend try looking out for this, in case it is somehow GMR interfering. I was thinking it might be since the problem seems to happen in-between turns which is handled by the app.

I just want it to support Beyond Earth multiplayer games, but I guess we're waiting on Firaxis before you can make that happen :)

I've had this happen in vanilla multiplayer so not sure it's a GMR thing.

I'm playing a game where we've reached endgame, it's around 1995 (turn 275) right now but since maybe the 1700's I've had a bug where I cannot receive or send any trade offers. Or rather, I can send and receive them, but the ones I send are cancelled with a "Deal no longer valid" once my next turn comes up and the same thing happens if I try to accept one sent to me.
Needless to say, it's rather annoying to have this handicap in a game that I've invested almost 300 days in :/
