"Character with that name already exists" - Bank Tab issue?

Made already a post in the Legion Remix forum and there’s at least one post from another player in the US-Forum, but I leave it here aswell:

Seems, that editing either the Character Bank or the Warbank causes a soft-disconnect. I observed it for a while, since I usually have no such behaviour and didn’t change System or Interface recently.

Right clicking a Tab is save so fare. But when I change options, name or Icon, I am desyncronize and can’t

  • log out properly
  • interact with NPC’s
  • use Portals
  • use Items or Spells (note: Friend of mine got the same error, did a teleport to Shattrath and then after coming back online the Spell was unlearned)

The issue replicates to 100%. So for all of you, who had these type of disconnect, try to remember, if you changed something on the bank settings beforehand. And let the Support know.
