Yea , sometimes there is various reasons one cannot up their version , so if they are at some of the older versions then they can’t use the newer stuff , like I am at 4.20 , but there is an issue with navigation invokers when moving up versions (i’m still trying to sort this and move at least to 4.22), but yea, generally I was referring to the epic content. Though even for marketplace content , it would seem more engine versions might mean more sales. As there are a couple later version things I would buy if I could use them.
