I've not checked but doesn't this only add limited collections data so
whilst it fixes -b, it potentially corrupts the cache for the non -b
cases?

This is definitely something we should fix, I just want to make sure
this doesn't corrupt something else. I suspect it deliberately doesn't
write to self...
