Okay, I'm trying to understand what's happening, so bear with me. So there is the "Your Purchases" tab on the Marketplace. You go there, and you're seeing the items show up. But they don't have tags, because you haven't tagged them yet. I assume if you tag them with something they show up there with those tags correctly. However, in addition to "your" tags, all the Marketplace assets have "global" tags that are set by the Marketplace author. So for example if the token is an orc warrior it's probably already tagged as such and you don't have to add your own "orc warrior" tag to it. However, those tags will not (and never have) shown up under the "Your Purchases" tab, they show up on the Item page on the Marketplace, though. What I *think* you're saying is happening is that in the in-game "Art Library" search (when you're actually trying to add stuff to the tabletop), the Marketplace assets are no longer showing up correctly when you're searching for their "global" tags (the ones the authors added to them)? So you're having to go and manually tag your Marketplace purchases before they'll show up in-game when you search for things to add to the tabletop? Am I understanding that properly? Assuming that is correct, can you try changing the search drop-down where it says "Tokens" or "Maps" to "Everything", and then try searching for the author name of the asset or another keyword and see if that fixes it? You shouldn't need to do that but I'm wondering if something got broken someplace. If that doesn't help either let me know.
