Does BP store references passed to its custom event as inputs

Does a reference passed as custom event input gets stored along with the BP object? I’m using a customized GC and it’s trying to GC the object referenced by custom events

Not quite sure what you mean by stored. Stored with the BP, nope.

I wouldn’t rely on the above if I were you. It will work fine in a function for as long it’s in scope but how long Custom Events cling onto the references has always been a tad of a mystery to me.
