I have seen this issue at well in the 395. Mostly in the 2nd car where the face to face seats are on the right. I don't have a screenshot but I saw it today. And sometimes when I interact with that seat the camera faces wrong way. Is there anyway to fix this bug, I know it is a minor bug to be concerned about and very few people owning the Southeastern High Speed DLC have faced this issue but it just sounds rather strange so it would be better if you could give a solution.
I believe this issue is caused by the Class 465 seats being in the wrong direction if you go to sit in some of them you lean forward and others you lean quite far back into them
