One thing I noticed that is probably of interest...
Code:
[05.07. - 02:44:06] [WORLD__CLIENT_ERR] username: Received unknown EQApplicationPacket
[05.07. - 02:44:06] [WORLD__CLIENT_ERR] [OpCode OP_Unknown (0x6a5f) Size=8]
[05.07. - 02:44:06] [WORLD__CLIENT_ERR] 0000: 49 42 b8 78 d9 42 b8 78 - | IB.x.B.x
[05.07. - 02:49:35] Unable to convert EQ opcode 0x6a5f to an Application opcode.

[05.07. - 02:49:35] [WORLD__CLIENT_ERR] 0000: 41 03 11 06 8c 03 11 06 - | A.......
Not sure what this means but it probably provides a clue for those who know the OpCodes.
