Bug Bones in skeletal mesh are moving upon import

Hello,

I have set up a skeletal mesh in Blender and I am attempting to import it into Unity via FBX. I have been able to successfully import the skeletal mesh without issue for a while. But recently the bones of the skeletal mesh have been moving/collapsing around a single point. In fact the most of the subtree of bones except the Root bone for each front wheel somehow end up in the same exact position even though that is not how I set it up.

My rig in Blender:

My rig in Unity:

(the issue is also there when dragging the mesh directly into the scene)

The only thing that I can think of that could be a cause for this issue is that most of these affected bones exist purely for structural purposes and don't drive any vertices. The bones that appear to not experience this issue most have vertices assigned to them.

It is also particularly odd how this issue cropped up for seemingly no reason. It had been importing fine before, but now it's not. I have no idea what the trigger could be. This issue is causing my hinge joints to behave erratically where they worked fine before the issue appeared.

I just needed to change the pivot mode from center to pivot. Somehow it keeps ending up in center mode confusing me. Well, that solves that mystery. Turns out it's not a bug and it's just me being stupid haha.
