There's a gigantic lag between claims and update of the challenge page, can take an hour or more before you see a claim in the claims per day.
Also the multiplier "forgets" roughly half of the rolls you do, meaning you do get or lose the tokens in the multiplier, but in multiplier rolls per day or per month it counts only just over half of them.

Has happened before (a month ago or so if I remember right) and requires a server restart to fix it.
Since they do not have any kind of support, never read any of their email and they rarely check whether the site is working, it may take several days, if not weeks before they notice the problem and restart the server.

Not sure if it's just me, but I find it an extreme pity that one of the longest lived faucets on the web has such an extremely bad customer support.
