[2022] Unintended Knights nerf in last patch (non-beta)

After the last patch (Android, non-beta) I have several times (at least 3) had the following bug happen in multiplayer:

I am attacking with a Knight, killing several units in a row, when I suddenly get an error message when attempting the next attack. Saying something like "error sending command to server". I then have to quit the game. When I get back into the game, the knight is done moving, so I can't continue attacking

I have had plenty of connection problems and crashes in this game before, but the game state has always been correct after restarting, until now.
