When playing as West Seaxe my vassal Suth Seaxe greatly condemns any battle support I give them. We've been fighting a lot of battles together, but they seem to hate me for helping them. I don't understand that at all.
For instance, they had a 20 man army parked next to a enemy army of 10, so I parked my 20 man army next to the enemy to help Suth Seaxe absolutely crush the enemy army. When I looked at our relationship, " They condemn... Battle support for Suth Seaxe -50".
Seems pretty backwards to me.
