There's 2 strange lights under each freight car in the center. The light shines through all objects and nothing blocks the light from appearing. Seems to not do this on 3 Bay covered hoppers and I believe intermodels. -xbox series x
This happens to the Class 66 fuel tanks and the MFA freight wagons too, I'm playing on Series S. I also play on PS5 and it does not have this issue, seems to be an Xbox problem.
Can confirm this on Series S too. Every time a freight passes you, you can see the strange light under each wagon and looks like it’s clipping through the wagons.
Exactly the same problem on Series S. It's like a flickering texture from grey to white, sometimes semi-circle shaped, underneath the middle of all freight wagons, which even shows up OVER the in-cab instruments. EDIT: I got a video of it, which you can see here (from 21 seconds in, the first part of the video was also to document the pop-in on Series S)
I played it first time earlier after finally installing all my routes from tsw2. Its on the class 66 only, that has 2 half circles things under the loco and what ever wagons it has pulling. Am on series x.
