Stop trying to fix your map Boomer it ain't broken. I think the issue here is the amount of maps in the rotation . Yours more then likely the one that put it over the limit. What happens (and I think this is what happened) Is the mod reads all the iwd from all the maps in the rotation. When you add up all the xmodels in all those maps your over 100. Cod4 is so long ago for me but what I think the answer is is to place a blank arena file in the mod iwd. Or maybe remove some maps from the rotation or it might be to place a blank arena folder in your maps iwd. I'm sure Rugger knows all about this. Maybe he just needs a reminder about it. Still I think its my best guess. Hope it helps.
