I have been playing the mod for the past few days and it is truly my favorite. The new aux player feature is great, however I have noticed a reoccurring bug.
Afterwards, after a large battle where I have died and took control of another player, it keeps telling me that the enemies have 1 player left (and I must choose to charge them 1000v1. When I enter the battle, that enemy shares my appearance (looks exactly like my character, armor and everything). This was as of build 79, so I am not sure if it has been fixed or not.
