When I log in with my tamer mage character my back pack isn't opening. The primary problem is that the delay before the pack open instruction is sent isn't long enough. But I just figured out something interesting today, how long that delay needs to be depends on the size of your character data file. As Lucitus can attest, the character data file for my tamer mage is very large, and the delay needs to be at least 2.8 seconds. I'm guessing that a delay of 3.2 seconds would account for even the largest character data file.
