I've installed the latest gamma build. Stubby and so forth are all running.
I get a load message saying that Enchantrix isn't loaded, and /Enchantrix works (prompts to load always or load never). I assume this means Stubby has done it's work and is trapping /Enchantrix calls as expected.
However, Auctioneer does *not* appear to be stub-loaded, and the /Auctioneer slash command doesn't work (so, obviously, I can't /Auctioneer load or /Auctioneer Load Always). Opening the AH doesn't change the situation.
