Can't see friends general in adventures without revisit same adventure.
i send invite friend accept invite and if i stay in adventures whole time i don't see his general when arrive. for he everything is normal. i can't see if he attack something, if he kill something etc. after revisit i can see his general and can see what he do in adventure.
This not happen every time, but is very common
also i think because of this now is more adventure have locked zone.
