Hey TJ, thanks for responding! I would modify the struct by either adding a variable or renaming one. I understand that if I were to change the variable type or remove a variable, that pins to that variable should break. Though the behavior I’m seeing is that if the struct is modified at all, then the pin to the struct in my blueprints gets broken even though it would make sense for them to remain connected. (ex: Variable A in struct remains untouched but I added a new variable B to the struct - Variable A’s pin would break regardless). The bigger problem I am facing with it is that even after reconnecting the pins when opening my project, they break once more when I close down my project and reopen (even without modifying the struct further). Almost like the blueprints didn’t save the pin connection.
