Significant bug: I had 3 healing potions on my character, I tried to split the stack from the crafting screen, but it didn't work. I tried to split them in my regular inventory, it didn't work. I tried to split them by shift-dragging them to another portrait, and it still didn't work.

Then after I gave up and left the inventory screen, my character could not move. Clicking just placed destination waypoints everywhere, but she couldn't move. My companion, the Red Prince could move just fine and my other character followed, but I don't want to play as the Red Prince. Lucky that I have a previous save game just before that.
