This is not so much a bug bug but I guess more a missconfiguration by the developers.
When you pause a recorded game, the game pauses.
When you, during the pause, open the statistics to check what the upgrades are on the units, the game continues until you close the statistics again.
Can be reproduced in every recorded game.
The pause doesn’t matter, either via the pause button on the keyboard or in the recorded game with the II
Edit:
When the recorded game is ongoing and you view the statistics, the game is paused.
When closing the statistics, the game continues
Edit 2:
When the game is paused, the game also continues when opening the menu. So apparently it’s with every menu.
