Common ProblemsI've lost all the minis I had but the achievement shows I have collected them.
We have received multiple reports of this issue and can confirm it is not working as intended for transfers between WoW accounts, though it is intended for the minis to not transfer to a new Battle.net account. Currently, we do not have a workaround or resolution that can be provided. We apologize for any inconvenience while our developers work as quickly as possible to resolve the issue.
If you discover a new issue, please submit a new Bug Report.
Note: Bugs submitted in-game do not receive a personal response. Instead, they'll be directed to the teams responsible for addressing them.
