Angel tombstone ward skin gone?!

[Client] Okay I bought the Halloween Skin ward, the Angle Tombstone Ward skin, around season 4 and now its gone!

What happened?! where did it go? I spent good RP on that thing and I want it back :(

In fact it is not just gone from my owned ward skins, but also gone from the store.

(Edit)

after more digging I have also found out my Season 3 ward is gone as well, THAT is not cool!

I always have that ward on my Championship thresh skin which I got the same day I got the ward skin.

however as some have pointed out, The firecracker ward they bought is gone for them, but its still available for me since I never bought it. it seems only limited time ward skins have vanished from the game, and not just me. meaning this is a bug on the clients end.

(Edit too the edit) Alright, so Riot knows of the problem as seen here on Riot support page. The Problem is known Which means that if you wish to follow and see when this is fixed this is the best place to look. Apparently this is been happening since two days ago.

Here's hoping things can get fixed soon, and NOT before the next patch
