The facts in your question are internally inconsistent. If you had a court date, appearing on that date was your priority regardless of other issues.

You need to talk with an attorney licensed to practice in Kentucky and familiar with the Boone County courts. There may be a warrant out for your arrest. Should you have been terminated from an Ohio diversion program before your successful completion of the program, your plea of guilty would be accepted by the court and you would be sentenced on your criminal conviction. The dismissal of your case upon successful completion of your diversion program would no longer be an option.
In your case, you are a no show. Warrants are issued in Ohio courts for failures to appear. Imagine that is the case in Kentucky.
The judge in any court, Ohio or Kentucky, will wonder why you did not call the court or exert any other demonstrable effort to try to comply with the terms of your diversion. You may qualify for a court appointed attorney. Maybe best to turn yourself in and let the process run its course. You would be well served to be advised by a Kentucky licensed attorney from this moment to the finish line.
