Has anyone started looking into player inventory yet? I started with player gold, and tracing backwards discovered that there is an ActorCommonData structure (that does not appear to have an associated RActor) for the GoldCoins actor with an attribute set to the player's current inventory gold balance. I haven't determined how that ACD is referenced, though. I assume there is a container object storing all of the player inventory items somewhere, and one of those inventory items will always be a GoldCoins object, but I'm still working off a bit of assumption.
If anyone else has worked on this already or wants to collaborate on a solution, let me know.
