Blueprint cannot save when a function from a function library is present in the blueprint unless any alteration is made within the function library. Once editor is closed and re-opened the user must make a slight change to the function library to be able to save again.


Currently, the workaround is to disconnect and reconnect a variable, then compile the function library. This allows the user to save the blueprint until the editor is closed and re-opened again. In attached project, this is a change made to the function library titled StructureFunctionLibrary located in the shared folder.
