Some observations based on my taking a chance on your raffle.
Prior to me entering the raffle, all winning chances were either 50% or higher.
0x61Ec39942476D93C475f91ACA2fAE062d64B250c placed a bet for 0.01 eth 4 days ago on May-10-2018 10:57:44 AM +UTC
I placed a bet for 0.012 eth on May-14-2018 06:01:01 PM +UTC
The raffle drawing took place on 3:07PM. (counting down of 5:00 minutes to 0:00).
There was a dialog box that said "raffle drawing in process. please wait" (something similar to that. I didn't write it down).
After waiting for about 10 minutes of waiting with nothing happening, I walked away.
I came back a few hours later. I saw "You won 0.022 ETH" dialog on left bottom of my screen. When I clicked on it, it disappeared. When I checked my address I saw that no deposit came in.
We are very sorry that the web interface indicated that you won while in reality it didn't happen. This might be connected to the fact that the tab was not active for a long period of time, so I'm not sure if the win event was properly recorded by Web3js. This will need a little investigation.
