I already restart my wifi modem and reboot my smartphone but its doesnt work, maybe there something upgrade happen to windice right now because not only me experienced this problem I also ask this on the chatroom and same with the other the dice didnt work.
If the site feels so laggy admin/moderator there will refresh it with a notification to players before/after the page refreshed.
Just try it now and everything will be fine. Enjoy rolling your dice.
