Hey there,
Thanks for your report! It seems similar to saintlol63’s, but I haven’t been able to reproduce the issue on multiple machines.
I just noticed that some links might not have updated properly. Could you please check the latest demo link to see if the issue still occurs?
If the issue persists, a quick list of steps to reproduce it would be super helpful—I’d love to get this fixed as soon as possible, I already have a small update lined up to improve multiplayer and some other topics. 
I’ve also updated the docs and now offer Discord support alongside email to help resolve issues faster.
Thank you for your help! 
Cheers!
