The bridge ip command is implied as it's the default behaviour, but sometimes
the router gets stuck with "no bridge 1 bridge ip" but doesn't show it in a show
run.

Not really - the CPU is having to process every packet it sees on the Ethernet
in order to build the bridging table. NAT may be a better solution to your
problem if that's possible. (Static NAT from the old IP to a new one. I think
the router will proxy-ARP for the NATed address by default.)
