[OPEN] attacking allied cities the same turn your ally left

Bug Report

Expected behavior:
attacking an allied city in the same turn that the ally left the game, shouldn't be possible even after refreshing the game. (that's my understanding of how it should be... correct me if I'm wrong)

Actual behavior:
but if you refresh the game in such a case then you can attack the cities of the ally that just left. All those moves will get canceled if you end turn.

Steps to reproduce the behavior
1. create a game with atleast 3 players
2. player 1 and 2 ally
3. player 2 leaves the game a turn after he allied player 1
4. player 1 refreshes / reconnects the game in the same turn that player 2 left the game and tries to attack his city which the game allows you now.
5. all players end turn
6. and the attacks from player 1 on player 2's cities will all be canceled

Attachments:

player 1 (blue) and player 2 (green) are allied


player 2 leaves the game


that's how attacking player 2 looks before the refresh


that's how attacking after a refresh / reconnect looks


all those attacks will get canceled and the units are back to their initial positions

I'm glad you mentioned this.. this is a long standing annoyance - must be a good sign that Dave is fixing things if it's being reported in bugs ♥

(hopefully it's an easy fix...)

Oof, thanks for the info. Seems like a pretty clear bug... It's on my list now
