I think this might be the same issue as 987839, but that was reported using the older API, not using the new memory profiler, so I would not call this as a duplicate. See more info at https://forum.unity.com/threads/wip...analyzer-for-unity.527949/page-2#post-3619123 However, I doubt this is really By Design, even though the older issue was closed with this resolution. We are getting references (like 1000+ references) to every terrain Mesh, even thought the objects that allegedly reference it are GUI objects etc.; you can find the one real reference (MeshCollider) between the references as well, but the rest are nonsense and should not be referencing the Mesh. I have uploaded a snapshot from a real project where you can check these wrong references with the bug report; you can find it as Case 1115073.
