any object with more than one version, if a copy is made, the copy cannot be synced.
- create an object and edit to get at least to version 2
- (optional) sync the object to bring both servers up to date.
- make a copy of that object
- sync the copy: the event fails
the only exception is if the original object only has version 1. then the copy has version 1 too, and sync is successful.
