New Patrick O'Brian novel or thread about playing the video game Sea of Thieves?

Excerpts from the lengthy thread:

I'm playing alone on a small sloop and scouring this shipwreck for this special chest, and another sloop starts heading toward me. I know exactly what this means. We all know what this means.

And they keep a bit of a wider circle around the volcano and it's not really working, and embers are raining down on me and I know I am going to get hit soon.

So I do the next best thing: I drive into the radius of a second volcano. Two volcanoes for the price of one.

A chest.

Not THE chest.
