I had a game were we had a long pause because my opponent had to go to the washroom, I waited for him, but when we resumed the game, my resources display started being desync for the whole game.
Whenever I had less than 200 of a resources, if I tried to purchase something with it, it would let me click on the button (it was not grayed out) but then immediately remove it from the queue. So I had to wait until I had a lot more resources to buy anything, it was extremely confusing the whole game because I never knew if I would be able to buy something or not.
Went like that for the whole game after the pause. My units movement were not desync and moved correctly.
