2sneaky: I think means that the Generic Shooter template does not work in 4.15 without changes, so he wonders if you can convert the Generic Shooter to a 4.15 build that stills shows the error. That would at least be a bit smaller than my 10GB project to work with.
My guess is that it has something to do with convertion of enums from an old project ( < 4.15 ) to a 4.15 project and then nativizing it. But that’s just pure speculation on my part.
