[problem solved!] the Ogre Kingdoms mod has suddenly collapsed in my game--any ideas?

Could do. It's not the norm, but I guess the only reason why not is that sometimes updates can be applied fine without wrecking a game - in fact you potentially fix problems. Also it might get a bit confusing.

I guess not, but CBM uses it to good effect

I can't really follow this thread, but I can tell you this:

As long as the version number doesn't change, you can unload change, and load a mod during a game, and it will work. (This is what I had to do with UlmCivilWar).
