This related thread from a couple days ago compiles some issues. Here’s that plus some stuff from this thread. These issues seem to be a combination of patch 9.0.1 and character services, particularly transfers, and the issues affect all characters on an account.
- Collection upgrade missing (pet cap increase)
- Ability to pet battle (have to do starter quest or purchase training to battle, but some accounts are unable to progress the starter quest)
- Pet battle dungeon quest reset which results in no ports to the dungeons
- Minion of Mayhem title missing
- Lost progress on Riddler’s Mind-worm
- Lost progress on Uuna (a completed Uuna seems to have retained her cosmetic changes like the wand, flower crown, etc.)
- Island expeditions quests reset
- Warfront intro quests reset
- Rescue MOTHER from Uldir reset
- Azeroth Minis collection removed/reset to 0
- Legion hatchling quests reset (Snowfeather, Sharptalon, Bloodgazer, Direbeak)
I’ve also been affected by many of these issues after transferring characters. I was able to unlock pet battles again by paying my 8 silver at the trainer, but haven’t attempted to have a GM restore capacity yet. I anticipate that the devs will implement a comprehensive fix so we aren’t all piecemeal filing tickets as we uncover issues. Thanks for helping to forward these issues to the devs!
ETA: there are still issues, as indicated downthread. I unlocked pet battles prior to this post, then transferred another character and lost pet battle training on my account for a second time. I assume that would have impacted any of the other documented issues if I’d had a GM fix them.
