So I managed to get as far as depth 7 today. Would've gone a whole run... but then something happened.
Me and another guy who joined my party (didn't get to catch his name) were cleaning house, wiping the floor with mobs of Gremlins. We were about to finish slaughtering the whole bunch...
When the server rebooted.
Now normally, when you get disconnected from the game in the middle of a dungeon run, you reconnect right where you left off unless your party decided to disband or leave you.
What happened here was that the server reboot caused EVERYONE in the dungeons to be ejected back out into the Arcade. EVERYONE. When I reconnected, I must've been surrounded by about 30-40 other users, and that was just on ONE Haven!
So yeah... this is a problem that Sega really needs to correct, or else it could piss off a LOT of people.
On the plus side, I got to craft four more items today! And I got enough money leftover to buy three more recipes! Now to wait for another filled energy bar and go back in...
