"KHRC says machines improperly include races with scratched horses.
After determining the historical racing machines at a new Churchill Downs Inc. facility improperly include races with scratched horses, the Kentucky Horse Racing Commission has fined the operator $1,000 a day and is considering shutting the machines down until the problem is resolved.
In an Oct. 26 letter to Churchill Downs racetrack, KHRC executive director Marc Guilfoil said that the commission has imposed the fine for every day the facility has been open since Sept. 10—which would be around $50,000—to licensee Churchill, because its Ainsworth Game Technology brand machines used at the Derby City Gaming facility in Louisville are improperly including races with scratched horses in determining winning payouts."

Imo (as a software developer) you'd like to think something like this would have been caught in early testing -- or at the very least -- BEFORE going live.
