Same problem here. Tested in different computers, different accounts, different games, same problem every time (since about last weekend in my experience). Something´s clearly broken, I filed an issue but had no response (other than the automated one). I think Roll20 should at least acknowledge there IS a problem at confirm they are trying to fix it. As an aside, just in case a Roll20 developer reads this, when let´s say user A rolls their 3d dice (and then they stay on screen), and then user B (in the same game) rolls theirs, 3d dice in user A interface disappear (as if their interface was trying to show user B roll). So user A interface is somehow receiving the order of "some other user has rolled their 3D dice", but it´s only being able to remove old 3d dice, but not showing the new ones.
