Consistent, replicate-able DX Error with Gathering Log
I have figured out exactly how to trigger the DX Error crash related to Gathering Log.
Step 1: Open Gathering Log.
Step 2: Navigate to the Skysteel Tool page. Select the item gathered in the Diadem. (It may happen to any item gathered in the diadem, but I've only personally confirmed those.)
Step 3: Close the Gathering Log.
Step 4: Re-open the Gathering Log.
Your game will now have crashed due to a DX11 Error.
Please forward this to the people that need to see it for fixing. I have made a video demonstrating it, and I've had several friends with different setups re-create it.
