We will investigate the intermittent publishing problems. If anyone can provide information requested by How to post a Bug Report, that would aid in helping us identify the issue(s).
As for the publish window kicking you back a page if you’ve used SetPlaceId, that seems like an entirely separate bug (at least implementation-wise - not necessarily feature-wise). Can you provide more information on why you use SetPlaceId? This was not originally meant to be used by developers, so we may just lock it down to prevent getting Studio into a bad state if it’s not too important.
