I put this on technical page put i'm wondering is this a know issues or random, where you can't move the train you want to detail left or right and can only go back and forth by zooming in and out while having it well to the right of the screen or doing a wide circle around it.
They probably know about it, along with all the other issues with the tool, but it's very low on a priority list. Like how livery editor 2.0 disappeared from the roadmap, never to be seen again. This with the camera pan freezing and layers seemingly corrupting, becoming ungroupable are my biggest pet peeves.
