Just noticed it. Gonna try to work on a fix now ASAP before there's angry people here :). Why can't they just stick to one format.

They claim they fixed it already so I guess you just need to empty the cache. AFAIR time-to-live is 1 hour right? :)

Gonna go restart the server.

Seems to be fixed, but probably wouldn't be a bad idea to make it more robust in case of unexpected errors such as this 👍 . @BostX
