Using References as a (kind of) runtime set with nullable

[ysftulek]

I am using characterReference for storing my ray hit target, then calling event when that data changes using my variables onValueChange event, thanks to you, but the problem is I can't use this variable as a runtime set because

1. I can't make it null when game stops and onStart
2. It also can't register the same variable twice, I know that you intentionally wrote the script that way so we can't put the same variable twice in there, so then you may tell me use event for that, why you are storing that reference. That's good offer and it solves these problems, I can just pick and send that type to event but I also want to have a reference of it, it gives me more flexibility to work with.

Can you suggest me what can I do in this situation? Thanks again for your work, I really love this asset.
