"man://*(1)" [Not edited] --No lines in buffer--

Hi all - not sure if the following is a bug or not.

After saving and loading a session with a visible, loaded “man://*(1)” buffer (any man page), I get the following message upon entering Neovim:

".nvim/init.vim" 2554L, 112687B
"man://tmux(1)" [Not edited] --No lines in buffer--
Press ENTER or type command to continue

If I don’t manually load the buffer, save, and reload the session again, there is no message and the buffer is loaded. If I save and load again, I will get the message again, etc.

Was wondering if anyone had any ideas.
