turns out it wasn't the whole DC thing causing the CTD. It was my trying to issue a command for the ship assigned to the tactic to head to the contact's location when the contact was NULL. Game doesn't like trying to figure out NULL contacts

I've been testing this for about 3 hours now and it's stable

I've added some new tactics and roles to the ships in v0.0.6. I'll be uploading it here very soon.
