Gateways dont update themselves
So like one of my modems crash, and then I replug it in and then it works. However pfsense does not see this, I have to go to routing and then hit save on one of them and then it refreshes. I am on pfsense 2 RC4, but I doubt this was fixed, and I do not want to upgrade if it hasn't since this is nice and stable.
Also I should note that modem is in load balancing with another modem.
Sounds to me like it's not so nice and stable as you say…
Perhaps this behaviour is fixed in the current release?. Maybe you should test that in a lab?
