Interesting. I will take a look at this.

It looks like when you do :set nobuflisted | set buflisted it triggers the BufDelete event. I have tried checking if the buffer was actually deleted using nvim_buf_is_valid and nvim_buf_is_loaded, but it doesn't behave quite as I would expect.

I'll loop back around to this and take another look.

Can you try with fix/53-no_detach_when_nobuflisted branch?

Since :set nobuflisted triggers the BufDelete event, I added checks to see if the buffer was valid and loaded. From my little testing, I don't think this affects anything else but please try it out and let me know.
