If i have a feature class within a feature dataset in a GDB, find/replace the data sources does not work to remove the feature dataset and adds it anyways. The new sources don't end up switching, because it is still looking for the feature dataset
example:
Find: "C:\Users\me\Documents\Projects\working.gdb\FeatureDataset\FeatureClass"
Replace: "C:\Users\me\Documents\Projects\archive.gdb\FeatureClass"
Replace actually comes out like this, and does not update to remove the feature dataset: "C:\Users\me\Documents\Projects\archive.gdb\FeatureDataset\FeatureClass"
