nimsuggest exits with errorcode 143

[observant2]

• nvim 0.4.2
• Windows 10
• ConEmu, Powershell, GitBash (console doesn't matter; error is the same)
• nim 1.0.2

When I open a nim file there is no autocomplete or anything.
When I close nvim, I see an error output:

nimsuggest instance for project C:\Users\blablabla stopped with exitcode: 143

This exitcode is rather normal. It's 128 + SIGTERM(15), which is basically just neovim sending the termination signal to nimsuggest. I probably should patch nimsuggest to handle this signal.
As for autocomplete, how did you set it up?
