Landscape keeps moving location even after locking actor movement

Hi there,

I was wondering if anyone knows a solution to this or if it’s a bug?

I noticed my landscape had moved down further, I ended up moving it back to the position it should be (it’s an ocean) then I selected lock actor movement and everything seemed sorted, saved and closed.

However each time I close UE5 then re open my project it has returned to that location again…

Any ideas?
