I am currently playing a long endless Veles adventure and I ran into a weird Ogre Ambush bug. Since I had Veles scout the area, I knew that the Ogre Ambush card was coming and I put on my best equipment. I wore the Gluttony Armor (which was undamaged and showed 52 for the defense), Knight's Helm (undamaged at 10), and the Hellion shield (undamaged at 20). However, instead of giving me a high defense number the game said I had a negative defense of 135. As a result, I got a lot of pain cards and almost died.

Fyi, I have previously encountered the Ogre Ambush card during this run with the same equipment and had no problems. The only difference I can see is that I did an amours restricted adventure a couple of adventures earlier and then got my Gluttony Armour returned to be undamaged. My guess is that I will sell the GA and see if getting it back later solves the problem.
