^ I'm not finding it connected to thread length at all. In fact, its totally random. When Yuku has a moment, nothing will work, I can't even get onto FOMM like you. I think we should be precise about this. Making loads of duplicate threads when we haven't determined thread length is the actual problem will be an admin nightmare.
For me, its totally when Yuku servers are having a splutter and its random luck what will or won't load.
