Describe the bug
QuickQuest addon loaded cause the crafting UI to close on every first craft bonus item crafted.

How to reproduce
Take a profession and craft any item for the first time with QucikQuest loaded.
My specific case was enchanter as 2nd profession.
Problem goes away when disabling quick quest.

What did you expect?
Not my crafting UI to close.

Screenshots
Can't really capture it, video maybe but not sure it will help much.

I doubt that is because of QuickQuest, have you tried doing first-time crafts with only QuickQuest enabled?

Addon related to crafting I have installed and running are TSM, CraftSim, CraftScan and Profession Shoping List which is not showing in the addon file indeed.

No but I have been doing it without QuickQuest and the problem is gone.
Maybe it's indeed an interaction with some other addon, I can't tell.

here is my AddOns.txt file in case it can help.

This is what I'm assuming, and trying to find out through you. I've been doing plenty of first-time craft without any issues, and because of this you'll need to find out which addon is interfering.
