Steps:

1) Got Freespace Open
1a) GoG Freespace 1. Already owned.
1b) GoG Freespace 2. Now owned.
2) Got FSPort, to play Freespace 1 in Freespace 2.
3) Kill every single drone in Mission 3.
4) Statistics show no shots fired, no kills.
5) Fail mission, despite killing every drone.

Help?

Played it again, no problems. *Shrug*
