Comments bg color acts strangely about onehalf HOT 4 OPEN

Hmm. That's interesting. I reverted back to an earlier commit of the plugin and it fixed it for me.
In .vimrc/init.vim
Plug 'sonph/onehalf', {'branch': '5bec08d', 'rtp': 'vim/'}

I did a little more digging and the latest commit broke the comments:
* 141c775 - (grafted, HEAD -> master, origin/master, origin/HEAD) Italicize vim comments (#101) (1 year, 1 month ago) <Jason Wang>
If you remove the "italic" portion, the comments highlight as expected again (which is basically the same thing as using the previous commit).
Change
call s:h("Comment", s:comment_fg, "", "italic")
to
call s:h("Comment", s:comment_fg, "", "")

from onehalf.

opening my editor using the exact same vimrc, just nvim instead of vim, fixes the problem

I have the same problem. I've been using the color theme for quite a while and never had this problem, but I reinstalled all my plugins and I think it updated. I see the problem on nvim and vim. I'd love to know what happened. I ended up doing the following, which is obviously not ideal:
Commented out the following line in onehalfdark.vim:
call s:h("Comment", s:comment_fg, "", "italic")
and added
highlight Comment ctermfg=247 ctermbg=236 guifg=#919baa guibg=#282c34
to my init.vim
I stripped my init.vim/.vimrc down to just the plugin manager and this theme and it still had the problem.

im not entirely sure what the problem was, but i also noticed i had a separate colorscheme plugin with the same theme name that might have been causing conflicts
