I like to take pictures in each of my runs through Oblivion, so I lay hand an each pose mod that I can find to collect interesting poses. Sometimes I stumble over poses, that, when started, show a slight, or more often, a silly grin on the face, that makes that pose near worthless for me. Also, whenever a pose starts this smile/silly grin, each other pose that I start thereafter has the same smile/silly grin on it, even if this other pose, started directly, usually has the 'normal', neutral look in the face. I always have to reload then and to avoid the 'infected' pose that I can use at least the other poses, but unfortunately, see 'Murphy's law', the 'infected' poses are always the better poses, never the one that you wouldn't use anyway...
Does anybody know where I can find the reason for that silly grin and change it back to 'neutral'. I guess the information that I search is stored in the .kf-file, because it starts always when I use the same single 'infected' pose. So Nifscope may be my friend, but till now I was not able to find the place with the responsible informations. I also tried the tab 'Face Animation' in the CS, but that hasn't changed anything.
Any hint would be much appreciated.
