This has happened twice. Once in the Gobliln Camp and now at the battle at the Druid Grove Gate.
During a battle the character can suddenly not move. I click for them to move somewhere and the line and circle show up, but nothing happens. They can still use their actions, etc. they just can't move. Then, after the fight, they still can't move. I move everyone else and try to go to camp, but what I've found in both cases is the unmoving character gets pulled through space and often ends up getting caught on some part of the world. The most recent event was pretty funny, because it pulled me through the Druid Grove and I ended up trying to stop the biting of the kid who stole the relic. No one else was there, just my main character talking to them out of context. Anyway, not sure why this keeps happening, but it does.
