I’m seeing a lot of crashes with the message below when I add new Replicated variables to a class.
Basically, it doesn’t like when I add new replicated variables to a class. The way to fix it is to delete the binaries and intermediate and regenerate C++ classes.
However, this is an annoying problem that’s popped up with UE5, and was never there in earlier engine versions. Is there a better fix for this, or does it deserve a bug report?
Thanks!
