Completely different bugs. For instance your stats loads, his doesn't.
The problem with rollin.io is probably because of the exploit recently found on Rollin that cost them 25 Btc. I'll have to review their changes and update the bot accordingly, so until I release an update, rollin will probably not work on the bot.
Thank you very much, I surely gladly want to donate because of that. Starting from faucet i gained 10mBTC by your bot in rollin.
