Pretty consistent and happens with both vim and nvim. When I navigate up a directory in NerdTREE the devicon is missing for the directory I was just in. Fo.r example, in the screenshot I just navigated up from the teams directory.

This also happen when I add a new file/folder. As a quickfix, I have found the reload action (Shift-r) in NERDTree to display the icons back (for the files/folder that had missing icons).

@aminnairi Good idea. Since I was already using chdir mode 3 (which changes CWD when going up/down a tree), the following helped me automatically refresh:

let g:NERDTreeChDirMode = 3

function NERDRefresh ()
  if &filetype == "nerdtree"
      NERDTreeRefreshRoot
  endif
endfunction

call NERDRefresh()

I think it's similar to this problem.
