Ok, I checked and here is the answer:
We had a problem over the weekend with an affiliate sending through funny ascii characters in their tracking tags, this interrupted the stats procedures from running every hour, we have fixed this now and taken counter measures to prevent this happening again. All stats were kept during this period and no data was lost. All stats were back as soon as we deleted these weird characters in the CID code.
The pop up transfers your CID, so if you send players to Geisha and they click on an exit pop up and download bingo liner the code is transferred. You can test it, by simply doing that, please make sure you delete your cookies first.
He also says:
“My job is to increase affiliate commission as much as possible, I am incentivized through remuneration to do this. So I would NEVER dream of decreasing an affiliate commission, I want them to rocket. I get paid more when you get paid more.
I will do whatever I can to increase your commission, which you can see through my constant CPA competition incentivization.I am sorry about the stats being down, but we are running 24/7 and things happen
