I opened Overwatch this morning to make a Custom Game preset I was thinking about, and I noticed that some of my saved presets were gone. I used one of the missing ones last night, and it is not one I would have deleted. I did delete others manually recently, but that was days ago.
Before I noticed they were gone, I had been playing in the Europe region, which I do early in the morning for quicker AI games. Usually I play in Americas, but swapping regions hasn’t affected this before.
I do not have much more helpful information.
