I got informed from some users the stop at win target sometimes or often not execute the first time the target is reached. I never saw that on my computer.
I suspect the event consumed or had to low priority, so the next spin could run instead of stop.
I have done some change in the code to put the event at first priority.
Please update the bot if you see problems using the win target.
