I can confirm this seems to have also happened to me on Switch. I explicitly recall starting logging in on switch just to get the founders cape and just now noticed that it vanished.

The 10 year anniversary world seems to also be gone from my account which I'm fairly certain I had also downloaded.

Solved for me. I still find it very questionable that the marketplace does not provide any sort of proof of purchase for any free items.

This is also happening alot on a realm I play on. Ive noticed it happening alot when interacting with things like chests. Also being in the most "populated" area of the realms seems a bit like its also making it happen more often, I cant confirm that well tho.
