Version 1.33

I'm not sure what caused this. As I have not been able to reproduce it.
It happened when I switched from blacksmithing to smelting (using profession links on my hotbar), but this is the first time I've encountered this error.
But I got 2 errors at once.

It seems that skillet after encountering these errors is in a complete broken state. Every time I click another trade skill it repeats the first error. Closing skillet and re-opening restored it to normalcy.
I presume it has something to do with loading data from the server.
Very strange.

First, I'm not going to do anything with a one-off error on 1.33. Clearly the client was confused by the data the server presented to it.

Second, Auctipus is a relatively new Auction House addon for which a new Skillet-Classic plugin was developed. With Skillet-Classic-1.37-alpha8, the plugin loads on my system and generates no errors with or without the addon installed. The plugin is referenced in the .toc file and should exist in ...\Addons\Skillet-Classic\Plugins it exists in my archived copy of 1.36 so if its not there on your system, I suspect you have a bad install.

After upgrading to 1.36 (after switching characters) In the same session, I got this when I logged on to any character.

(Looks like a pretty useless error, no information at all really).

The rest of skillet appears to be working as normal, and I don't see anything listed in my crafting queue, so I'm not sure if anything is trying to trigger the auctionator shopping list frame or not.

Well, I didn't get the auctipus error when loading on the PTR with alpha 8
I'll try on the live realm in a moment.

Yup, the auctipus error is gone now.
