Hey Widdle Kitten,
Nice Summoner Name, I'm not too surprised you purchased the Pumpkin Cat Ward. It is something that my colleagues are looking into and is something the Server Status Page notification was vaguely referring to. I took a look at your account and can verify that you do have the ward skin, but where you'd find it might be a bit surprising.
In the meantime, if you purchased it and re-logged, you should be able to find it all the way at the bottom of the Wards Collection page when looking through the "My Collection" selection:

In Champ Select, similarly, you can locate the Pumpkin Cat Ward Skin all the way at the bottom of the list:

Since you've already crafted it multiple times, please create a Support Ticket so my colleagues can help you with that: https://support.riotgames.com/hc/en-us/requests/new
