Adding and removing AttributeSets has problems about gasdocumentation HOT 1 CLOSED

I've actually concluded that using separate AttributeSets on weapons is not a great idea. The main issues are that changes to an Attribute from a GE must go through an ASC and we can't target a specific AttributeSet if more than one of the same class exists on the ASC or the AttributeSet is removed from the ASC but still valid in the world. This causes:

1. Complications with multiple weapons in your inventory.

2. If you remove an AttributeSet before an Attribute aggregator change is replicated, the replicated change will not find its AttributeSet and crash the game. I ran into this with a rocket launcher killing myself and removing the AttributeSet on Unequip/Death before the ammo change replication came in.

There are probably ways around these issues, but I find it was much easier just to use replicated raw floats on the weapons for magazine ammo with an Ammo AttributeSet on the Character for reserve ammo (this allows weapons to share reserve ammo of the same ammo type). I'm led to believe that Fortnite also does its ammo this way with raw floats on the weapons (I'm unsure about their reserve ammo).

My next sample project coming soon is an advanced FPS that shows this functionality and how to work with it in GameplayAbilities. I'll update the README when its released.
