This bug rarely happens (only happens twice for me), sometimes in seal arena your friend not start at respawn base instead he started outside of respawn base at the beginning of fight.   If he(bugged person) pro of course he will run immeadiately and regroup with his team, but if he noob he gonna take that seal and get raped by enemies in 3 vs 1 battle. And in the middle seal fight our team will be raped in 3 vs 2 battle.
