Not sure if it will help but I do have all the previous morostide skins and they are still checked as green. So I do not believe this to be a sitewide glitch.

They are not cleared; once you have unlocked a skin, it should be unlocked for you forever. Could you please file a ticket (just say told you to, and please list which skins you are missing again) and we can see about getting them back for you.

[edit] Wait, sorry! I've been told there may have been a time (before I joined Subeta!) when skins were only active during the holiday and not unlockable. Let me check on this and get back to you.

I looked into this, and skins actually did not used to be unlockable; they used to be temporary, or last only until they were rezapped or cured. It looks like 2014 is the first year that Morostide skins could be unlocked in the wardrobe permanently. Do you remember around what year you got these skins, because maybe that is what happened. The skins you feel certain of were all released pre-2014, so it's the most likely explanation. Angelic was released later, and Fevermore is a later Survival skin (not Morostide), but it sounds like you are less certain if you had those two?

(Sorry - this was actually something I just learned today. I joined Subeta in.. I think 2016, so after those changes were made!)

Zapper skins are definitely not temporary; once you have one, it's unlocked for you now.

The notification you got is actually about the human zapper buff expiring. There is a buff that can trigger that gives you a free zap at the human zapper, but expires if you use it after a certain amount of time. I guess the phrasing is a bit confusing - I've just tweaked it to be less ambiguous about it being a buff that's expiring!

Regarding getting a zap and nothing apparently changing, I think this may be what you're running into: Zapper bribe gave me repeat skin

Going to close this up since OP's report was addressed. If you have other issues to bring up, please make a new topic if no topic for it already exists. Thank you <3
