These are just mostly minor issues, I'll find more bugs when I play more:
1. Tehlrog Castle - in my allied campaign assault against Tehlrog, my troops seemed to mistake the ladder for a siege tower, and they just stood still and did nothing.
2. The dagger item - when you draw out the dagger, the dagger is still in it's sheath.
3. "Ruler of player faction" When you go into the encyclopedia under "characters," the player is "the ruler of player faction."
4. "Your mercenary service contract to {playername} has expired." When your mercenary contract expires, it says that my contract was to myself.
5. During a mercenary contract - "blank", I humbly request my weekly wages. The blank is supposed to have the king/khan/queen's name, but it's just a blank followed by a comma.
6. Fur Coat - it has an encumbrance of 16 kilos - that's far too heavy, that's almost as much as some of the metal armors.
7. As Darian said, the follow and capture the spy quest is still messed up - once you reach the spy, you'll just find one spy, and once you kill that party, the other spy party is right underneath it
, so as long as you succeed in tracking the spy down, you can't fail the quest - there's no time limit, it seems.
