I have the same problem.
The 10105 and 90000 don't happen all the time, but I still can't play because of this strange and persistent communication problem.
It happens only with my main character, he has this stange lag, I can't attack monsters or open NPC stores, because there will be no response from the server.
Any other character plays fine, smoothly, in the same server or other server.

The problem PERSISTS if I log on another PC, I tried another PC and a notebook. Just with this one character.
My friends can log on my PC and play just fine with any of their characters.

Only my main character is unplayable, on any machine, since yesterday.

I played with an alt for about 10 hours with no problems, and then, before I went to bed, I tried to log my main. I could play without the problem for about 1 hour! But today, after playing for 10 minutes, I started a Roulette Guildhest and started lagging. After exiting the instance, the character was unplayable again, and the situation persists.

I started to play this game 2 weeks ago without any issues. Until yesterday.

Anyone?
