After booting up freespace since finishing the first release of derelict 10ish years ago, I'm enjoying this saga with the SCP. Finished FS1 and FS2, ST:R, TVWP Act 1, and now I'm trying Derelict SCP. I am now having the same problem I had 10 years ago. In the second mission, I am tasked with pushing "1" to drop a nav buoy. It didn't work then and it doesn't work now. I got around it years ago by cheating and using FRED, but I can't remember exactly how, and I would prefer to play it in game.
Does anyone have a clue why, even after all this time, my number key can't do the job?
