I am not sure what the correct way of reporting a bug is, please let me know if I can report it on GitHub for better visibility.
When I review a game and I use the left arrow key to navigate the move trees, my branches dissapear. Moving with the right arrow key in a forward direction is fine.
What browser and operating system are you using? I’ve been unable to reproduce this, though apparently it’s affecting several people so I’d love to get to the bottom of it.
Also, if you could link me a review where you reliably see this that would be very useful. You can PM it to me or paste it here.
FYI @LeSac while I’m still unable to reproduce it, however another team member finally was (though not very reliably yet) so hopefully we can track it down.
The root cause was related to analysis being disabled for the game under review. @LeSac, since it happened for you on every review, I wonder if you have analysis disabled globally in your preferences?
Regardless, if someone is still seeing this, please report, since it’d be a new/different issue…
