Static mesh components spawned in the UCS along a spline require lighting to be rebuilt after a map reload.

Seems to be somehow related to components being instanced in the Construction Script according to a spline. The transforms are slightly off by more than 1.e-2f. They are reconstructed on load with a non-default transform before being reattached to a parent Actor, so maybe it is somehow related to that. Will require more in-depth investigation.

1. Load sample project into the editor.
2. Build lighting.
3. Save, then relaunch the editor.
4. Note that "lighting needs to be rebuilt" even though it was rebuilt in the last session.
