Yesterday I've played 2 battles (Ecorcheur vs Ottoman and Debitre) and had the same problems :
- Some player couldn't join their faction (even being accepted in the roster ) => sometimes it happens when you change fief/attack/transfer things and try to leave/join a faction in the same time
- Banner invisible in the menu, or different banner => dunno why
After quiting and rejoining :
- all skills and attributse are at 0 (impossible to take weapons or armor) => happens to me often, its mainly serverside that doesnt load your char and need to rejoin until it works (or wait a bit for the char/items to load)
