I use Neovim as my daily editor, it definitely has it's quirks over Vim (sometimes it takes over 10 seconds to write to certain files, locking up Neovim and there are some bugs with the fuzzy finder I use that cause file corruption that aren't present in Vim) but on the whole it's pretty stable. Haven't encountered any issues yet that are more than a minor annoyance.
It's a third party plugin, it's definitely a Neovim issue because the file corruption doesn't happen with Vim. No idea why it happens. I'm fine living with it because I just check the file back out if it corrupts it. It's only an issue when opening a new file so it doesn't cause work to be lost.
