Militia mission wont register as complete

[Deltax]

So I was playing through transcendence 1.2 and just reached st.katharines star, I went to get the militia mission as usual and was told to destroy a sung slave camp, yet after destroying it I got no "Mission complete!" message and the dude at parliament is still saying I haven't complete the mission. Bug?

I'm playing with no xelerus mods btw, just the official osaka extension.
