I found another bug...
After you get the Cursed Eagle and then Zulwhern, the Cursed Eagle still be in your party, like a 6th char, and if you enter in the town where you buy your house(it doesn't show the name...) and battle the Kitten, it'll lead to a series of endless battles(still winning the damn cat, you battle again...)!!
Luckly i had saved outside the town hahahahaha
