I am noticing that when I play a stone, within a second or so it disappears. Often before I can mouse over to the submit button. Also, if I use the Analyze Game feature, the same thing happens: stones are played and then disappear after a second or two. I have tried this one Mac Safari, Mac Chrome, and iOS. It seems to remember where I put the stone when I hit submit, but that is a scary way to play. Hitting submit and not being sure that the stone you played is actually in the right spot. Help. This is super annoying.
Okay. This was happening on multiple computers, but now it seems to have stopped. Odd.
