I don't understand how research happens. I'm getting knowledge points but there's nowhere to use them? Just started phase 4. Other than that, this has been fun so far, although I've been very wary of hiring workers because I nearly ran out of money once.
Edit: Now in phase 5, still no idea about research. Also I built an Excavation Rig but immediately it said all buried contamination cleared. That seemed like a waste of 80 scrap then. Where should I be building them? Not all zones even offer the option.
Edit: Nearly finished. Finally found the research! Lovely progression from cleanup to restoration.
I'm just wondering if there's a bug with energy generation. I built a solar panel and then a solar field, but my power generation is still 0. Also the wetland boardwalk unlocked before I researched Sanctuary Ecology.
