There may have been a loop in the VLAN corresponding to that ve 
interface, and DAD kicked in.  Removing and re-entering the IP address 
generally makes the router do another round of DAD, and if the 
duplicate address (i.e. the loop) is gone, then it will stick.

So check your syslog, and whether the output of 'show ipv6 interface' 
at the time of the breakage included anything about DAD.
