Ok, I found the issue about the missing refs, but the self ref is still not working properly.
Now the number of refs they keep is correct but they keep a self ref for each one, so 1 correct ref is lost for every bp that received it. I don’t understand why

What message do you see when you mouse over the Self warning?

Ahhh… I do get the error
You can’t have Self in a library function, basically.
But you can do this with a macro, so macro library it is…

so…my friend…that time has finally come..hasn’t it?

Because you don’t like macros?

no no, It was to laugh a bit. 
Because I guess I’ll have to delete everything and redo it. Never done a macro before, I don’t know anything about it. Should I be worried?

It feels very like making a function, but the code actually gets compiled into your blueprint graphs, whereas a function is actually a separate object.

I just thought of a way to bypass the self ref in the function, but I still want to try with the macro, also because what I thought is not very elegant perhaps. Anyway, thanks a lot for the help sir!

good morning @ClockworkOcean
I’m noticing that macro has not exe pins in input/output
Is that normal?
I manually entered the exe pins but now even though I recreate the macro variables in the bp, I have an error on them, and it also says that self is not valid
It’s one of the variable types
Self has to work, because a macro is literally just copied into your code on complile
To make the correct variable type, use a pin drag

While waiting for your answer, I solved it by keeping the function library, adding the ref as input, so now I will pass it between the bpi call and the function library call, so I have no errors of any kind. Now everything works, anyway, thank you very much! Maybe I need more time for the macros, to understand all the differences between macros and functions and exploit their potential to the fullest.

Yes, that was also an option
Generally, functions are better than macros. But it really depends on the situation.

I tried to make a very stupid macro because with the function I couldn’t manage the output with exes, at least I limit useless duplications of logic as much as possible
