Another much smaller bug. This time after using a scroll of knowledge (reward for the second bug in op) game jumped to a charecter screen that doesnt exist, was just able to close the charecter page, which returned me to the inventory screen showing me the results of the scroll, which worked on the correct charecter. Nothing broke like the last two bugs.
Also music randomly stops, not sure the cause. Opening the options menu seems to bring it back. I believe it has something to do with combat, because it just happened again after combat.
