So I'm saving a 10.4 mxd as a copy in 10.0, using the Save A Copy option. This usually works fine, but since I added a feature class with Editor Tracking enabled on it, it gives me an error when trying to save as 10.0:
BUT WAIT! Although the message says the layer (which has editor tracking enabled on it) won't draw when I open the new 10.0 MXD, that's not true. The layer does draw...
Why is this?
