Brad, Is it possible that during the original copy & renumbering, some (or all?) of the originally-placed components got renumbered/renamed? If so, an "update schematic" from the PCB might have helped. Just a thought.

Found an interesting (frustrating) issue when one changes between netlist and synchronizer updates to PCBs. Following suggestions from a day or two ago on how to get changes straightened out when the synchronizer tries to keep track of original component links, I used the netlist clear and then import a new netlist into the PCB to straighten out the netlist connections. This occurred when I copied already placed components in PCB to place a similar grouping of the same components, renamed them within the PCB to match the target netlist component designators, and tried to get the design synchronized. The original problem was that the synchronizer remembered the original PCB component designators and couldn't handle the correct manner of matching the newly designated PCB components. After loading the netlist to the PCB to fix this problem I cannot use the synchronizer because it still hasn't sorted out the component matching. I get two lists of non-matching components and a matched list which contains no matches. Worse then even that the two lists of components needing matching do not have even half the components listed in them and there are no components in either list which can be matched by the designators. There is not one single matching pair of designators in the reference or target lists. This is just a general warning or heads up about this issue. However, does anybody know a manner of getting these matches corrected and sorted out? I did try exporting the schematic, exporting a ver. 3 PCB (I figured a ver. 3 PCB file might free up the P99SE component matching) and bringing them into a new database. This didn't work. I get exactly the same matching results from the synchronizer. I finally made a copy of the PCB within the same database using paste special and then deleted the original design. Then I could easily match the components (C1 ... C1_1, U3 ... U3_1, etc.). But there has got to be a better way.
