The Roll20 Pathfinder Sheet is stuck saying "Building NPC" after dropping from compendium.

Hello, I have been struggling with this bug with the Pathfinder sheets by Roll20 for some time now where it makes drag and drop NPC's unusable. When I drag from the compendium into an NPC sheet, the block that says "Building NPC" never goes away. I have seen this issue posted here before and will start by saying I have no extensions active, am on the lastest update of Chrome and on Firefox, and do not have the sheets popped out in a new window. None of the other solutions I have read have worked, so I was hoping someone here might know what I can do to fix this issue. 

Does this happen with all things dragged from the compendium, or just certain ones? Does this happen in all games, or just one? Things seem to be working alright in a game of mine, but I might not be attempting to create the same creatures.

It seems to happen with creatures and not other things like spells when dragging them. Today it did that to a Rhino and an earth elemental as I was trying to set up some summoned creature sheets. I know it has happened to others though have no specific examples. It will allow them to work sometimes, but others cannot.  So far I have only seen it happen in one game, though will test in a personal game I make. I am a player in that game so that may be another issue, possibly.  Edit: After making my own game and testing a few drags, they all worked perfectly fine. This makes me wonder if it is related to a setting in the DMs game perhaps or something else. 

I had this issue happen when I went afk for a long time and returned. What I did to fix it was to close the browser and reopen. Everything worked after that. 

Unfortunately this problem has been going on for a few months, so closing the browser is not the solution to my issue. 

I am having this issue as well with my games. No pop-out. I've tried multiple different settings on and off, deleting sheets, re-adding them each time.

Current work around for me is to drop the creatures into an alternate campaign and then transmogrify them over. It seems the campaign itself is glitched.

OK. You should use the Help Center and Send a request to get Roll20 staff attention and a ticket to track your issue. Link to this thread in your request.
