I'm trying to buy the armory collection on the Epic Games Store cause it's on sale right now, but cause I already have the 30th anniversary pack, it's unavailable. Contacted Epic Games support first and they said I could refund the base game to see if it gets rid of the 30th anniversary pack and I could try to buy the armory collection after. Anyone have any experience with this, such as if I lose all progress or lose purchased expansions if Epic Games refunds the base game?
