Boy that's soooooooo frustrating ....
I noticed that since the tweak you made, the rate at wish the celtic event trigger for the player is near 0. I've played 3 characters and it never showed up (nor Bran's Ship), but every one else still dies, get double criplling or scars .... Etheir they die in an accident or from infected wound.
I'll try tomorrow and see if it turns out the same for feudal lords.
