Problems with entering Icecrown, with characters transferred from Neltharion

Hi. I have a problem trying to enter Icecrown with two characters transferred from Neltharion. I can not enter and the game closes, I think it's about leaving my two Neltharion characters in the Deepholder area when, I made the transfer, I think that could be that. since with other characters everything went well.

If there is anything that can be done to solve this problem, please tell me Thank you very much.

open a ticket in-game with a character you are able to log-in and ask to GMs to move your bugged characters in a different zone
