DHCP suddenly stoped working on all interfaces

[Assar]

Running pfsense 1.2.2
This is a description of a solved problem and a proposal.

Some days ago DHCP stoped working after a powerdown.
After a couple of hours of searching I had to temporarily replace the fw with a SOHO router.
Today I found the problem:
A couple of weeks ago I changed the IP on a unused interface.
All seemed fine and everything was ok. What I should have done was to also change the IP-range on the DHCP.
What happened was that the DHCP stoped working next time the DHCP-server reloaded.
This had consequences on all other interfaces.
This might be an obvious place to check, but my lack of experience prevented me from finding this right away.

Bottom line:
MANUALLY CHECK THE DHCP WHEN CHANGING IP ON AN INTERFACE.

Proposal:
A reminder or a warning on top of page when changing ip on interface would be nice.

PS!
Thanks for a VERY nice FW. pfSense rocks.
Continue the nice work!!!!!

You actually get a message when you change the IP on the LAN interface.
Although not on the various OPT interface.

Nice!
Did not try to change the LAN interface since it's frequently used.
Is this feature addable to other obscure interfaces to?
