During my siege of Flint's Finger I noticed that I was being shot through walls. So I wanted to show where and how you can go through the wall. It was very annoying during the siege and it made me lose a lot of troops.

Also at Storm's End when I took the castle and then had to fight in the Lord's Hall me and my companions were instantly killed for some reason. So I had to cheat and kill the people in the lords hall with the Ctrl+Alt+F4 cheat before we died so I could take it.
