Here’s one. https://online-go.com/game/7229394
It shows in my game list as yellow (which is what it does when you need to accept stones). Every time I go to it, it shows me as a red cross. The clock keeps ticking.
Added bugginess advice: on my phone, I can’t see the scores to accept or not accept. This is part of the general “on mobile, nothing next to the player avatar is visible, including their name” thing.
