It still appear, but it is just in a determinated point when I arrive on the boat to Borean Tundra. So, I can jump to the water or relog when the boat is in the docks and I can continue playing. Also yesterday I was playing with my horde char Palatrip in the realm Ragnaros and I was killing one of the bosses in the arena of Zul'drak (I think the forth, don't remember) and appears the same critical error. The same critical appears near TOC in the top north of icecrown. I have many error in the map, maybe is my client so I'll try reinstall the game.
