Yes.
when I changed my recipe, it automatically closed the current event.
I had to then load previous event as a reference map.
The problem is the current spray will not map on the reference map.
you need to go to the top left and select current product to see what you are doing.
Then you need to go back and select the last map to see what you did before.

it used to be that when you loaded a reference map, that became the background and everything mapped over it as if it was adding to it even though it wasn’t.
I did the split screen but still had to do a lot of extrapolation on the edges that were done or not done.
I don’t know if this was by design or they got it screwed up.
