Why is it renaming all our S feeders to G?! and what is a G feeder?
As soon as I pick an S feeder and update the coordinate, it renames it to G instead of S meaning all our projects now have random S9xx feeders instead of the correct ones.
What can we do about this!?

Well the problem is that that posistion in our projects now points to some random other south feeder and not the new, so for instance, the S20 changed to G20, but in our projects, all those parts are now assigned to Sxx meaning that a fully working project now doesn't work, and we have to go through all those parts and reassign them. It would e a lot easier if changes like this also was handled correctly, ie swapped S to G in the project files also, OR as a bare minimu, unassigned so that one know it is destroyed and needs work before it will work again...
