Hey,
Love your work, the addon is great, ive found a few issues though

Craftsim does not correctly calculate Profit for all Missives in Inscription (seems like some issue with quality?)
https://gyazo.com/985db9a1e6712f2219ea371ea500460f

Also with Combatant Gear (Specifically Crimson Combatant's Emblem)

It does not appear to be updating pricing data when using Auctioneer as source, idk if this is just me or something more?

Thanks

Missives:
Thank you for reporting that, I fetched the itemIDs for the different qualities from the UI until now, but it seems that sometimes the order blizzard has the item ids in the quality list ist just plain wrong.
I reimplemented this to, similar to gear, fetch the result items from the ingame api now and this is fixed now with 3.2+

Combatant Gear:
I dont really get whats the issue here? The quality 5 profit and the average profit resulting from it seems to be in line with the auctionator profit shown.
If you mean that after hitting search its not updating immediately, this is due to CraftSim not yet getting triggered by this search. You have to click to another recipe and back to refresh it (Or change any materials, or switch to sim mode and back)

If this is not what you ment, feel free to open another issue
