Most save errors that I have seen are due to overlapping roads that are not connected and junctions that have been moved which now overlay a geometry node. Yes, the spotlight would be helpful, but you can generally track these down.
Regarding geometry nodes and overlaying them when moving a junction - tip. I always hilight the segment that I am planning to move a junction towards to ensure there is not a geometry node close to the junction I am moving. I delete the geometry node(s) that will be overlaid by the junction (by pressing they keyboard shortcut 'd') BEFORE moving the junction. This avoids this problem.
Of course a reasonable workaround is not to batch too many saves together at one time. I try to keep it to less than 10 changes (especially when adding new roads or moving junctions) to minimize the frustration.
If you are renaming sections of road, changing road direction, etc - that is a lower risk change to cause a save error and reasonable to batch up more before hitting save.
Just my observation with tens of thousands of edits in the new cartouche.
