Can you be more specific when you say 'nothing happens'? If the 'unload' works chances are darn near everything in the Mist system is working fine. The unload process basically uses every component of Mist with maybe the except of one of the gates opening and it's corresponding OPto.
The unload test 'should' drop the ball in about the middle
Make sure the 2 OPs that detect which side the ball is on are working in the switch test menu
My best guess would be there's a problem with the mist harness or possibly the OPto opposite the said of the unload test. There might be a break in the hardness and possibly still making a connection until the motor hits a certain point...or in your case the right side gate for 'load'
