I think I've found it. What was essentially happening is the
workgroups are supposed to be deleted inside a loop:

for wg in workgroups:
    del wg

but this doesn't actually delete items from the list, of course.
However, because there was some deletion of things inside wg in that
loop, I think there were references that were left dangling. I'll
issue a PR soon for just that fix.

Regarding the duplicate halos, I haven't tracked that one down yet.
