So, I've just tested a situation with:
There is no problem at all. JQE360.com still have a point to Xboxunity.net Even when I manually point it, nothing changes. I still can download some of artwork, but no TU's available in FSD. Therefore, I suspect that this issue was implemented specially, to pull FSD off the road and to give a way for Aurora. First, the TU's problem, second - the LINK problem. Coincidence? I think NOT! Someone surely wants to bury the FSD. And I don't like this way of doing business.
