Thanks for the replies. I suppose a feature like that would work if all the players know and trust each other. Not great when playing with randoms, though, which is what us casual players do. The hosts of these games don't speak English and I am not committed enough to host.

Two games, both dual gap, my units or parts of my base have been transferred to another player, not by me. Surely this is some kind of exploit, because if it's a game feature it makes no sense?! Is it punishment for playing gap??

Replay https://replay.faforever.com/26496568
At around 33 minutes my bug gets transferred to Venividivici with no input from me.

Replay https://replay.faforever.com/26488804
Part of my base gets transferred, but the game is a desync, so can't see the replay.

This has happened a couple of times in the last week. No mods active. Here's the error in case it helps someone:
