Client Lost Connection....
You may have received your bank upgrade in your in-game mail (if you didn’t directly purchase it on the bank slot), try deleting a few in-game mails, specifically, the ones with envelope icons.
As for connection, I played most of the day yesterday and into the evening (okay, early morning)… Roughly around until 12:30am US server time and I had zero disconnects. The only time I got booted was for a patch update. I experienced a minor lag issue, but I’m not entirely convinced it wasn’t partly due to high population in the new zone and partly that my hubs decided to upload/download stuff while I was playing. I did have a nasty d/c the previous night that forced me to reboot and repair my client after a crash, but it was an isolated incident.
Part of the problem with ISPs is, they can only check the connection local to you, this doesn’t take into account nodes along the way to your connection destination. If a node along your path experiences overload or some other connection issue, it will affect your gameplay. (ex. When Chicago is experiencing a high volume of connections, my latency in game has great potential to sky rocket leading to icky input lag and jumpy/skippy baddies)
Also, playing over wireless connections can cause unforeseen issues to… Issues your ISP can’t really help with. Are you playing wired or wirelessly?
Let me know if you get your bank slot after you check the in-game mail bit.
