Quoted from sto:yes you started ea. Still dont think you did this by shooting under the right flipper, but to be honest, i never tried this...
If 5ym is ready, the machine will show you this very clear. The vengeance shot is lit very aggressiv. Only thing that i can imagine where you have 2 balls in play and nothing is lit(except an error), maybe you were in vengeance Multiball after defeating the vengeance.
Keep on trying and have fun with this great game
There is a bug in the code that prevents 5YM and even EA from lighting
