I'm finding I'm getting dismounted from my horse if I swap weapons while on horse. However it only happens when swapping to my secondary weapon set. Switching from 2nd to 1st does not dismount me. It also does not happen on one of my charcters at all no matter which I swap to.
It happens on the following:
1st = Axe/Shield
2nd = Restro staff
1st = Destro Staff
2nd = Restro Staff
1st = Sword/Shield
2nd = Axe
1st = Restro Staff
2nd = Destro Staff
1st = Restro Staff
2nd = Axe/Shield
It does not happen when
1st = Bow
2nd = Dual Daggers
