Resetting the AI..

[Bearcat]

I have several missions and some that are from FB 1.0. The AI seems to behave in the old way.. I am thinking that I may need to open the mission up in the FMB and edit it and save it so that the new AI behavior will take effect in it.. Is this correct or will it automatically be done as soon as the AI is tweaked in a patch? Do we need to "reset" the AI with every tweak on older missions? How about ones that may have been made under 4.11? Am I making sense..?
