Editing of linked component leads to weird behaviour of XD

Hey,

from today on every editing of a linked component in the child project leads to a kind of freeze of most functionalities.

By clicking on any artboard nothing happens, after i e.g. changed a string - also i can't choose any different object anymore. Biside this, it's not possible to go back or save anymore. the only thing i can do is setting different font styles.

I'm working with a cloud document and the behaviour appears on both platforms, OSX and Windows.
