Hello Irish Shoota,
Demerits can -, and bans will cause a blow to your dice (oldtimer score). Dots are deducted, and if there are no dots left, the dice is taken away completely. You don't have a dice right now but If you stay demerit free it will come back eventually.

The oldtimer score  is calculated mainly based on time spent by playing the games. 

Kind regards,
John

After speaking with the user he is talking about the "Progress to next level" within his profile, the % progress bar is not showing.

Hi Food Wizard,
it's not showing if the dice is gone.

There will be a progress bar again shortly before there's a new dice. But there are times where there is no progress bar at all, because it does not show a minus value.

Kind regards,
John
