We still get “No valid stuntparty, description, yeah” a lot of the time.
We still get invisible other players.
We get new screwups like “Round 1 complete” followed almost instnatly by “time’s up, 0 rounds completed” when the timer isn’t even halfway down.
This is PATHETIC.
True its still boned for me too on Xbox Series X. Its rubbish anyway, cant believe they add it into the play list. I never used to do the Forzathon in FH4 so to make people have to do it to complete the playlist sucks in my view, it pops up as a free choice in free roam and i prefer it stay that way.
Tried one yesteday and had to jump through targets one by one, once you smash the taget the next one appears, except it decided to not show the next one, just the ramp with nothing there, i eventually found the invisible target by randomly jumping in different directions off the ramp until you hear the smash sound…makes it a little more challenging i suppose! 
I joined just to agree. I did manage to actually finish on today, speed version. Then I was in one by myself. Just a few minutes ago, it was looking like I may have actually had a chance to complete a second one, the time ran out prematurely with about 3 minutes left to go. We were in the third round of a drift arcade.
