Same here. I have several outdoor scenes where I augmented the Sketchup ground with a Rocky landscape where I sculpted features I wanted. I open a file in 2025.1 and the landscape isn’t there. I found it off in space.
I hope an update fixes it as I can’t put the landscape exactly where it was. Everything else from the Sketchup stuff to the painted vegetation, water and whatever else is right where it should be.
