I have an issue with 4 of my characters who can’t use their garrison caches. They all have 3 tier garrisons but the quests are still stuck at setting up the garrison. Brymoel level 80 orc warlock, Monduiz level 80 forsaken death knight, Oyaminartok level 80 pandaren monk all on the bleeding hollow server, and sharlario level 70 night elf priest from the kel’ thuzad server. They were boosted in legion. I saw a post about the issue back in 2020 and was hoping the same solution could be applied. Resetting the garrison for those 4. I submitted a ticket in hopes of getting it resolved but the recommendation I received said to post about it. Ticket Number: US102424981 was my attmept. I saw that Vrakthris had helped a player called Felbud with this same issue september 2020 and was hoping for a similar solution.
