So a few of my playables started a Greek House and pledged a bunch of their cousins because they rolled the want to. Most of said cousins eventually became full members and moved in, but one of them I forgot about and he graduated while still a pledge. Now the former Greek House members still have the ability to influence him for 0 influence points.
Is there a simple way to fix this is SimPE? (This won't cause horrible problems in the long run, will it?)
