Structures returning wrong references in 4.17.2. Basically make a structure of static meshes. Copy and past that struct in the content browsers and then change the meshes inside it and the structs name. At this point you should have 2 unique structs. However, after saving and restarting the copied struct still returns the previous entries from the original.
I tested this by running the struct pins into a get display name node and then through a print string on tick.
