2 more bugs I came across: (you see the location on the screenshots)
-the AI of the undead mage especially at this location seems to be broken (sometimes undead mages at other locations behave similarly): most of the time he walks around doing nothing, not before you walk near enough to him, he starts attacking you and healing himself if necessary
-the other bug is concerning the hitboxes of rocks. They seem to be bigger than it should be
Spiegelberg! He, Spiegelberg! Die Bestie hoert nicht.
