Princes of the Apocalypse maps removed from VTT?

Quick search didn't reveal anything.  It seems that the maps included in the Princes of the Apocalypse campaign have disappeared from the VTT map selection.  I have the ones that I already "loaded" into the tool, but that campaign appears to be missing from the drop down menu.  Any idea if this was intentional or inadvertently lost during an update?

They're still there for me.

One thing to keep in mind is that if you don't actually own Princes of the Apocalypse, but only have access to it through content sharing, the maps from it will only be available in the campaign where it's being shared with you. It won't appear in the list in any other campaign.
