I've never had as many error code 630 as I've gotten in Virtual Planet Battle Training. Somewhere in the middle between Dekor Maryuda spawn and the last section of the Urgent Quest, there's roughly more than 70% chance of me dropping connection out of the blue for no reason. It is not my internet. It seems to only happen in the UQ itself as I do not 630 otherwise. Or happens very, very, rarely. Not this often at the same area.
I do not know if it's just me or if others are experiencing this, but some form of investigation may be needed. Thank you.
