You’re right about the Enthusiast achievement not working. Whenever I change characters, the currency number either changes or disappears entirely. This is a total circus, they may have fixed some of the issues, but there are many others which they may not yet even be aware of. Whenever I check the tab, something is wrong in a different way.
The only thing that consistently and properly works are the individual tasks which you’ve completed - they have a little green checkmark next to them and they properly keep track of everything. The bar at the top doesn’t always add up points properly and other time the whole thing is completely greyed out (says no gametime with active subscription).
Got my mount back when the first set of fixes went out but ever since then I cannot loot any new trader’s tender I earn from the chest. I hope this gets fixed in time before trading post expires so we can all get the rest of the cosmetics.
