I did some of the stuff here and haven't had one since (it's been at least several weeks).
Im glad for you bro, I've hardly ever had them, and now it's constant all of a sudden since last week.
I had 5 last night and just got another one now after being on for 40 minutes.
When it happens it's really annoying as it seizes all game activity but you can run around for 5 minutes at least while all npcs, clan mates, everything else is stuck in position. After about 5 minutes it finally gives the delta 03 error and are forced to log back in. Getting really tired of it
