I was just minding my own business grinding away pitiful amounts of 10 diplomatic xp per mission when I noticed something VERY peculiar during one mission. It was one of the "scan carnivorous plants" ones. This is what I saw: http://img37.imageshack.us/img37/6237/teveni.png
It might be a good idea to check through the missions to make sure only the correct interact object models are displayed, because this was very... I don't know, "what is this I don't even"?
I think actually each "bugged" missions needs seperate reporting, as they don't have a way to conclude on other missions. So everytime you see this, file a bug report. At some point, the mission will probably be fixed or removed. (I think it's the latter actually.)
