big problem with bp structures

this feature has a lot of bugs!
I trying to make my weapon pack and found a lot of bugs with visual bp in structures
Can I use one structure in another structure as variable?

Often variable lose direct link to structure and then disappears from variable list

Yes you can use a struct as variable in a another struct.
