Neovim Version (nvim -v)

v0.12.0

Operating System / Version

Ubuntu 24.04

Describe the Bug

With neotree visible on screen and close_if_last_window set to true if I modify a file and then try to discard changes and exit with :q! neotree does not close and this warning appears instead:

[Neo-tree WARN] Cannot close because one of the files is modified. Please save or discard changes

Now if I do :q again i get an error:

No response

Steps to Reproduce

1. Set close_if_last_window to true in neotree configuration
2. Open a file in neovim
3. Toggle neotree. I use :Neotree filesystem show left
4. Edit the file
5. Exit with :q!

Expected Behavior

Neotree should close cleanly. Note that:

1. If close_if_last_window is set to false i can close the buffer with :q! and then close neotree with another :q without issues but i want it to be automatic
2. :qa! always works without issues

Your Configuration

vim.pack.add{
  -- Tree
  {
    src = 'https://github.com/nvim-neo-tree/neo-tree.nvim',
    version = vim.version.range('3')
  },
  'https://github.com/nvim-lua/plenary.nvim',
  'https://github.com/MunifTanjim/nui.nvim',
  'https://github.com/nvim-tree/nvim-web-devicons',
}

require('neo-tree').setup({
  close_if_last_window = true
})

having trouble reproducing the error but this config option can definitely work better and avoid this, give me a bit
