I'm sorry, but this hasn't been fixed yet. My previews in the pop-up info have the same bug as before. In one game, I have a queen in the wrong column being available to be attacked by a knight (panic), but clicking on it brings the queen in safe territory. (254144) It's like the FEN isn't being translated properly, it's "off" by a column or something.
I hope this can be fixed. I didn't see anyone else reply to this message, so I guess nobody else has this problem, which I can't figure out, because it seems to be a server-side issue (my guess) rather than a cache or computational issue on the client side.
Check this out:
I'm not a great player, but why would I intentionally put my black queen there (254144)?
Look at 257939. We've made 3-4 moves! How could r be on a1 and a2?
Thanks for checking on this.
