Deleted firewall address list and loopback bridge vanished!

RouterOS General

Ok the first time this happened I thought I had a blonde moment but it happened a 2nd time to me today. The first time a few days ago.

I have an RB1100AHx2 with 6.7 software and firmware 3.10.

I was in winbox deleting a couple of IP addresses from the firewall address list when I suddenly lose contact with the router. I then logged into the router with a computer plugged directly into it and I find my bridge interface is gone! I have a bridge created with NO ports associated with it. I assigned a /32 IP address to it to act as a loopback interface for OSPF. Whats happening here?

I have 16 other routers that I made the same change to with no problems. This one router has done it twice now. Firmware problem? I’ve been using 6.7 since it came out.

Added info. I rebooted the router in the middle of the night and ended up with 3 bridges when I originally had one. So when the bridge disappeared the previous two times and I added a new bridge each time these were recovered after the reboot. Any thoughts?
