Thank you for your feedback, Red Queen! I never had much problems with bugs or missing scenes before, but strangely enough the last patch has made matters worse for me.
The occasional bug with non-climbable ladders or non-opening doors now occurs every time, and some cinematics are missing.
I hope the climbing problem can be fixed before release, falling down even a small ladder almost kills my squishy sorcerer 😄
(Although the trick to use Jump at a point near the upper end of the ladder works quite well)
