I had recently seen that D/GG/Circa was making some updates to their One Card system. The web portal was down for maintenance for a bit earlier this month (August 2020). I have also heard about and now witnessed (I am in town visiting) some machines not ticking up points on the card reader as one plays. Poking around the menu of the card reader, I found tier points there alongside current slot points (total covering both casinos). I happen to have 1000 tier points, per the card reader. Tier points do not show up on the web portal, and the tier points did not tick up as I played last night. I had heard about D/GG/Circa looking into a tiered player's club, right from the source at the top (mention his name to get a $25 match play). Just reporting this here since nobody else had yet.
