Trial of the Sekhemas

1) I wanted to put all the extra stuff in the trunk. On all other locations, the triangle key moves the item to the chest. But in the challenge location, clicking on the triangle removes the item! Even a quest item...

2) I ran out of honor in a challenge. I had to restart the game. The challenge continues, but all the buttons stop working. :(

3) Bug #2 happened on the challenge boss. My minions killed the boss while I lost control. After reloading, I lost the stone and can't start the challenge again. (This was the first attempt).
