I've noticed since the last update that trees will vanish and then respawn on Blackpool Branches as you approach them. I've noticed it happen on the section between Salkirk and Kirkham, and on the branch to Blackpool South. It's really noticeable if I set weather conditions to windy. So basically I'll be driving a service and as I approach the trees instead of swaying they'll vanish and then respawn in a new position a second or two later, almost as though the game can't process the animation.
