1.) Use an account effected by the issue (not mine anymore)
2.) Create a VRC+ Print, print it in-world.
3.) Check Prints via Profile -> Media -> Prints
4.) Observe print you just took is not listed.
5.) Verify print does exist via API, it is not being displayed in the UI, and thus can't be re-printed or deleted.
Additional info:
Something can be bugged with prints, after taking them, and printing them, they do not appear in your list of prints after a certain date, and so cannot be deleted except via VRCX, and cannot be reprinted later since they are not there.
This persists across cache clears and reinstall so I pretty confident it's not a local caching issue.
