Thats true, in my final I think there was a pile up at the left corner and there was a marshall on the track. I couldnt see my car so I ended up running to the back of Heath I think.
I wasnt too bothered tbh because the marshall was doing his job and Heath wasnt affected too badly.
I know there was an issue at the top right aswell but I managed to dodge most big pile ups, which is probably the reason I went from almost last to 2nd within 2 laps
I did see a role of tape on the track too, probably left after track repairs.
I think marshalls just need to get off the track as quick and as safely as possible. And when not moving try and stay low so not to obstruct the view of the track.
