Freezing Tavern not working end game

In Battlegrounds, I’m freezing the tavern and not all of the minions are staying frozen until the next recruitment round. The latest I took pictures of, but not sure how to include them here. Minions 1, 4, and 5 stayed frozen, but 2 and 3 were refreshed. I’m not sure if it was the same minion positions every time - I’d have to test it. It didn’t start happening until the last few rounds of the game.
