OK so, as the title states I've found myself with an invisible blue circle and the suggested fix ( game.party[0].follower_remove( game.party[1]) ) is not working. This occurred after I loaded my previous save during a battle which was not going my way. Meleny did not die during that battle and all of saves made before the last show her normally. ToEE Co8 5.9.2 NC BETA 7/1 player set up 2.8ghz Quad Core Nvidia geforce 250 Windows 7 32bit (I apologize if this is the wrong place for this post. I could not find a place dedicated to bug issues; though to be honest I did not look very hard :-\. )
I would suggest reloading one of those earlier saves and going from there. This game bugs sometimes and does wierd stuff. Just the other night I charmed an assasin and it practically froze my game, everything was going so slow. I had to reload and redo that battle with out charming this time and I was fine.
