You could add a sathium deposit in the playfield.yaml, but you'll have to start over if you don't mind. I'd be happy to do it for you and send it to you. I would to see this worked on sooner than later. I hate the fact that you die and respawn. It should be game over, load from your last backup. Also, some diseases should work much more slowly- but never heal on their own. Like having the alien parasite bite slowly destroy your vision over several days unless you find an anti-dote. And the open wound makes you walk more slowly until it's bandaged. It's just too easy- unless you are talking about the insanely over powered alien sentry turrets.
