I'm having a problem. Earlier today I waited the 300 seconds and requested coins as usual. But the coins I had still showed up as “0.0” and it told me “There are no coins available!” Just now I tried again, and it tells me I've hit the limit for my IP even though I haven't even gotten any coins in well over 12 hours.

Edit: And now the 12-hour timer seems to have reset again. What's going on? The only time it should reset is when I actually get coins…
