Resolving Stronghold attacks through manual combat is not a good idea if you have guest hirelings.
First bug
Hirelings don't regenerate between manual combats and they can't be healed before combat. It is a huge problem to lose 3 guest hireling because the game does not indicate if their death is permanent. There is no way I can rescue them all, it's an attack from the Vithrack. The game should also hint in Stronghold - Status which hirelings are killed during manual combat or let us transform a guest hireling to a permanent hireling for a huge price or let us heal them in the hirelings controls for money
Second bug
After Fellow of St. Weidwen (guest) and Dunryd Psiod (guest) both died in manual combat they are still standing in my Stronghold. The hireling list do not mention them.
