Problem is simple, and isn't game breaking, just really stupid and annoying. All over the Imperial City, I have two types of guards constantly ramming into each other fighting over the markers they should be standing at. One I'm pretty sure is from OOO, as they're marked Imperial Warders and in really shiny white versions of the armor, the others look like generic guards.
The only mods I'm running that should have anything to do with the guards is MMM, OOO (yes they are both set to converge correctly), Reneer's Guard Overhaul, and possibly Better Cities. Anyone know of a load order issue that may cause this, or some mishap in the newest version of any of these mods?
