Missing (hidden, inaccessible) artboards
Some artboards are missing from my XD document. But when I select all (Ctrl+A), they re-appear transparent (appeared but not work-able nor clickable). But they're still exists in the prototype tho...
It first happened on my friend's Mac, when he realized he lost some artboards, he asked me to check if the same issue is also happen in my windows laptop.
We both use the latest version of XD

Same here! My co-worker downloaded the cloud file and discovered that most of the artboards were somehow set to 0 px width, but all the elements are still there. Hoping the cloud file can be restored ASAP!!
UPDATE: We just found that the symbols/components have been removed from some of the 0 px artboards.
