How does the hospital work
I built a hospital. It says I can restore up to 10% free and 70% with crystal. I see a lot of units on the crystal side but nothing on the free side.
I don't know if its related but after I build the hospital there was a caravan from some mysterious sector. The name appeared to be Russian. There was no info on the caravan only an arrow pointing left and another below it pointing right. After the caravan arrived I didn't notice any change to my units or resources.
PS: I also built a Black Market thinking it would give me discounts or something, but I don't notice any difference from the permanent one on the right tool bar. Do I need it?
