After "upgrade & install" reboot, VRRP interfaces missing

Subject says it all… I have a pair of CCRs doing BGP and using VRRP. I use Packages → Upgrade & Install to upgrade one of the units, which automatically reboots it. When it comes back up, the VRRP interfaces are simply gone. Their IP addresses still exist (and are set to “unknown” interfaces), but the VRRP if’s are just missing.

This just happened from 6.12 to 6.13, but it also happened when I went from 6.11 to 6.12.

1 RM wan-vrrp vlan2000 00:00:5E:00:01:01 1 200 1s 3 ipv4It’s a minor annoyance, but could be devastating if I forget to do that second reboot before upgrading the other router. Has anyone else seen this? Seems like a bug to me.

I hate to bump this but I’m still seeing it. Should I file this as a bug report directly with Mikrotik?
