Bobthefish no longer displaying correctly for Mercurial (works fine for git)

Question

I'm new to Mac (macos High Sierra) and have just discovered fish, Oh My Fish, and especially the bobthefish theme. It worked perfectly with Mercurial after I installed it but after a single reboot now I've lost all the colours, indication of source control status etc...

It still works with git (which I don't use, other than to demonstrate this issue!).

The problem turned out to be the ~/.config/fish/config.fish file (contents below). Somehow this disappeared at reboot. When I restored it I got the Mercurial version control graphics back. Note in particular set -g theme_display_hg yes
