There are two bugs I’ve encountered. After playing for a couple of hours I wanted to look up for how long my food would last, but hovering over the resource icons had no effect. No small window popped up.
At the same time entering locations became really laggy. I was attacking a bandit fort, but the encounter didn’t start. I clicked somewhere else on the map, nothing happened. I tried using ESC, then my brothers suddenly started moving to that point of the map and the time suddenly jumped forward. I tried a few more times to enter the bandit hideout and it lagged every time. Finally I was able to enter after clicking the hideout and waiting for around 10 seconds.
After the battle I traveled to the closest town and there was the same problem.
