so you can see we recognized the Opponent played h4 and then we logged Playing h8. but the last move OGS has is h4

the next line in my logfile is my bot crashing because it asserts that it's black's turn

my diagnosis is that we call https://github.com/online-go/gtp2ogs/blob/9478fd1c808dcb23fbc6c6d6c5d6b1f7a5a07e62/src/Game.ts#L585 which just calls https://github.com/online-go/goban/blob/311bdb5b4e1b62524d26e945c00602effa8dc9bb/src/GobanSocket.ts#L352 with no cb we should instead send a callback with an error handler, possibly via GobanSocket.sendPromise

I suspect this might be the same cause as #409

online-go / gtp2ogs

move silently fails to send #417
