Who the fuck flagged and quarantined you of All people?! Anyways, thanks for another weird but Impy/10 Game!
It's most likely the auto detection, but Itch never says how it works. I correctly guessed that it was the Steam link in "Girlfriend Saves the City" that flagged it, so I was able to fix the issue, but I'm don't have a clue for what the problem with the latest Vault update could be. Itch doesn't even show creators when their games are quarantined anymore, they just silently shadowban them.
