8.2.5 introduced an issue where your class and race (including faction) may not be picked up immediately upon login. this means any items that are dependent upon those things (tier sets, anything tagged horde- or alliance-only, any quests or items that can only be completed by a specific race or class, etc.) may not register as things your character can collect.

try reloading your UI (/rl), which may fix it. for me, it doesn't happen on every login, so relogging may also work (but reloading is probably quicker and more dependable).

if crieve has time this weekend i'm sure he'll try to debug the issue and get a fix out for everybody. i'm going to close this ticket as it's a known issue that will be addressed ASAP. thanks for the report, and sorry for the inconvenience!

Thanks for you fast answer! Reload Works!
