Send me your savegame before this battle. So that I can reproduce the problem.I replayed the battle a few times on both WSE2 and normal warband and the difference is quite large, I gain about 10 points on average from 480 on WSE2 compared to 0-2 on warband
the kill count feature i added to my mod isn't working with WSE2.
Will be fixed in next update.Also someone has reported to me that the coin sound that plays when you earn some money after battle isn't playing at all.
