Yeah, that's freakin' weird! I've never heard of that. I use the same mods but not Oddballs'. I also have Difficulty Grade Changes, Grenade Range, and More Uniforms.... Keep us posted.
And you shouldn't have to restart to test this out. Use the AddMod
Tool to take mods in or out really easily. Just put the tool in your main S2 directory, start it up, select the latest save from the drop-down menu at the top, and swap mods around. Sweet!
