A few notes:
1) If I accidentally hit one of my own units, it just follows me (at 0 range) as if he might want revenge, but just can't attack since we're on the same side
2) Valahir starts friendly with the bandits around their area. This is not necessarily an issue (since they are all vikings), but I can never get negative relationship with them (so I can gather prisoners):
- If I help them, I gain relationship with "Valahir"
- If I attack them, I lose relationship with "Outlaws". Even though I am at -80 with outlaws, They are still friendly.
