AddonSkins gone from Tukui Client?

I've been getting ingame errors for a few days now about AddOnSkins being out of date and in need of an update - however every time I checked the Tukui Client it would say it was Up to Date.

Today, though, I started the Client o make sure my addons were up to date and found that AddOnSkins isn't in my list at all - it also doesn't seem to show up in Browse anymore. ProjectAzilroka also seems to have disappeared entirely.

They're both still detected ingame, so now I'm worried about them falling too out of date to work, with me having no way to update them.

Is anyone else encountering this issue?
