I did have the router ID set on both routers, with their respective loopback interface IP's.

The highlighted area below, from your config, is where I see 0.0.0.0

   --- OSPF Neighbors for Instance 1/Router ID 10.255.255.5 ---

NeighborID      NeighborAddress Pri State    DR-State IntfAddress     TimeLeft

10.255.255.12         10.0.1.9               128 Full     Other           10.0.1.10             34

have you got set the router-id ?

(config-ospf)#router-id 10.255.255.5

if not, ospf take the ID from ip address on loopback interface

0.0.0.0 looks like area id :)

try to set router-id
