Pushing out some fixes that should make this cache invalidate a little bit faster ahead of some more deep changes to how it works

This issue has been fixed... sort of! Read on for important info about how this works now:

In a nutshell; this is a cache issue. The wardrobe wasn't updating its item lists every time a new item's added to the site.

Ideally, we would update this cache every time a new item is added. However, I predict that this would cause severe lag if we actually tried to do this right now, due to how our code is structured (it's split between two separate code bases, old and new).

We'll be able to do the ideal solution after enough old code is transitioned to the new code! In the meantime, I've made it so that it will automatically update the items list every hour, and only once per hour - which means when new items are added, at most you'll have to wait about 1 hour before new items show up.

This frequency is subject to change - I think hourly will be okay and not cause noticeable lag increase, but I'll be monitoring this and will make adjustments if necessary.
