Same issue still persisting. Super frustrating.
Am able to save and package to own computer and able to save to server but unable to package to server. Please solve this issue as it really does hinder a good workflow.
Running MacOS High Sierra 10.13.3 can't get my hands on the beta 10.13.4, but as others write, it doesn´t really seem to make any difference anyhow.
