There is no bug in the autobet and it has been used to place billions of bets without error. It is most likely that you didn't set it up correctly to do what you thought.
Huh, isnt that weird. Someone lost everything using YOUR bot. Damn snake oil salezmen and their convoluted UI's designed to make people lose. Use a real bot that is so simple to setup that all you have to do is run it and thats it. No "setup" required.
Auto-bet is extremely simple to use. It's not uncommon for people to try and get a refund by inventing a bug when they lose.
I agree that bots can be a great alternative to auto-bet and provided you take all the basic precautions that are essential for everyone handing Bitcoin to ensure their safety. They can be a lot of fun but untrusted 3rd party applications should always be fully scrutinised before use.
Never use a bot that you cannot compile yourself. The source code should be available to inspect before you risk compiling and running it on your computer. If that is not the case you cannot guarantee that it doesn't contain malware that could steal your funds or even a keylogger that could compromise every other account you own.
