... my good party doesn't get the option to kill him, the dialogue goes as far to the "third share" and from there, you must accept an item, cause demanding it all only reverts back to the share options.
Yep, I would call that a bug.
My criticisms (so far) for v2.3:
Miscellaneous Enhancements: Ribald isn't
wearing an Archmagi Robe, I was able to pickpocket it from him.
Booter: I have some suggestions:
Carrack has only been imprisoned for a very short time, so there's no reason for him to suddenly become a withered old man with a long beard. I'd keep his avatar as that of a Male Human Fighter (I think that's what he is), and make him a Ranger, giving him the ability to Stealth out of the prison, making his exit from the Guildhall a little bit more believable.
I would alter Carrack's "I had a small cache of potions and equipment" line slightly, to mention that he was keeping them at a friend's house; not only is this a plausible corroborative detail, it gives Carrack a place to hide out while plotting his revenge.
The Trap blocking the stairs in Carrack's house should be auto-disarmed upon entering the building.
It would be nice if at least
some of the thugs sent to Carrack's house were legal Thieves, not guys decked out in stuff that Thieves can't use.
I would double-check the placement of Booter-on-the-rack: In my game, he appeared not on a table, but on the ground
next to a table. Also, when speaking to him, his first line is the groaning in pain that you'd expect; but talking to him again starts him off again about all the prisoners he's tortured.
