I was just looking at that and I used 127.0.0.2 without an explicit mask 
and the system picked /24. I'm not sure why I did it that way but it's 
been awhile.

I just got rid of lo2 and made 127.0.0.2/32 an alias on lo0 and it seems 
to work better all around.

I guess the overlap between 127.0.0.0/8 and 127.0.0.0/24 was problematic.
