Do I need to worry that the project view no longer displays the board

[PW_VOX]

Earlier today I hit the dreaded schematic/board synchronisation error, which a couple of opening and closing of the project fixed  as it often does.  However the project now looks like this

I can access the the board from the browser but the board isn't displayed.

@PW_VOXa，if you can access the board file, you don't need to worry about the preview. Most probably a bad preview image was generated for some reason. Can you edit/save the board again and see what will happen? If it won't fix the preview issue, you can just create a new electronics design document, then link the schematic and board document into the new electronics design file.

Thanks, it suddenly reappeared this afternoon after 3 or 4 saves.  I was worried that I would end up with schematic and board layout out of sync.
