When a mod update is rejected from Thunderstore then it disappears completely until it's approved again. This will happen every time YPlayBoombox is updated and can take up to half a day to be approved manually.

If you want to share a profile code with this mod with your friends and it's not available during this period, then they may need to update their profile again with the same code once it's back up on Thunderstore.

Sorry for any inconvenience caused!
