After patching today (v1.4.0C) & starting a new session, all of my in-game character names & in-game account name changed. Battlenet still shows all my correct info (CharmedCha0s) but none of my character names are the same & my IGN changed to “Chabi” – and. I. did. not. do. it.
Now, to complicate, each of these differently named characters had my exact character gear, aspects, account items Paragon board, button mapping, emote wheel & abilities on-bar.
(Was there database consolidation & the dynamic / cross-linked UID’s weren’t updated?)
