I was running some random contracts last night in sandbox mode. While en-route, I saw a vessel without IFF, so I entered EMCOM mod. I immediately got a hail from a ship. It was said it was a representative of the system or something, and I had the option to report a pirate in the area or say oops my finger slipped. I decided to report a pirate in the area since the ship without IFF appeared to be intercepting me, but as soon as I select the sector the game crashes.
I restarted the game and tested some things out. No matter how I disable coms, either with EMCOM or disconnecting it from engineering, I get hailed by an authority ship. It also always crashes if I report the piracy.
I can send crash logs, but since it has done it every time, it should be easy to re-produce.
