This really isn't that difficult is it? I mean Blizzard just said he like cross-linked the methods for the two scripts, or something like that, so they didn't interfere with one another. I don't really know anything about scripting, so I don't know what he did, but he made them compatible, except for this glitch I've found.
All I need is for them to work together so that the game doesn't crash when the player accesses something like a "potion" from the battle-item menu.
