When you attack a dungeon with a bloodhound, if you use the tool that shows you the path, the ghost changes the position of the bloodhound ! None of the other traps react to the ghost, and I don't think that the bloodhound should.
The screen often moves or closes when I use the mouse in KoT, so I use the keys to simulate the mouse's clicks. But since the last update (12/05/18), they are hardly recognized one time out of ten. Actually, even the mouse itself is not always recognized : ten minutes ago, I had to left click three times before my dungeon attack begins, whereas the clicks worked perfectly when I tried to open the locks just before.
