Objects losing their transformations in scene when re-opening saved file A couple of imported objects (.fbx) always return to their original location (center of the scene) as they were imported when saving and re-opening a scene.

I tried to apply transform, scale and orientation using ctrl + A without any result.

What could be the issue? I feel like I'm running out of options here.
FBX files often come with default pose "animation". Make sure the objects don't have animation keyframes. You can tell if the location boxes in the properties-panel are yellow or green. Also if navigating between frames with left / right arrow keys causes them to reset.

As for workarounds you can make a new mesh object like a cube and navigate to "Mesh" tab and use the mesh dropdown to select the mesh of the imported object. That way you should have a clean, unmodified object using the imported mesh.
