Thanks! I went ahead and posted in the Bug Report section with all the specifics.
Since you asked, and in case it somehow helps to include the affected characters/realms here too, here they are, sorted by realm.
Icecrown: Yelizaveta, Siobhann, and Mirabeau;
Earthen Ring: Tizziee;
Fenris: all except Emeleth;
Feathermoon: Nhimue;
Scarlet Crusade: Therie;
Antonidas: both toons
It seems like there may not be much that can be done from here but I think I’m more just hoping for some confirmation I’m not just losing my mind lol after not finding much of anything online matching my issue, which is why I replied to Vrakthris above to start.
