my standard operating procedure for blueprint structs is that if I am using one in some graphs and i want to change it’s variables, I make a new struct and replace the old one with it.
I do it this way because of the problems with them becoming corrupt like this.
I also try not to use them in general. At least for my project, the only utility I see in a struct is mostly minor convenience, so I just don’t bother with them. Perhaps there is some deeper functionality about a struct that I don’t understand though.
I’ve also found Map variables to suffer similar problems, so I do the same thing for them. If I have a Map variable in use in some graphs, I make a new one and replace the old with it if I need to make changes.
