Solved What the heck ? IR tech tree solving problem

[CodeNamed1]

So I’m confused I have almost completed the Industrial revolution (I think?) as I’m only missing 4 buildings but I can’t build any? The ones I’m missing are: 1, the other from brewery (I have distillery)

2. the other from crystal cavern (I have recruitment statioon)

3. the other from plastics and polymer ( I have medical plastics)

4. the other from crude refinery ( I have fuel depot)

I have all of the rest build in various settlements and all 4 are ready to be upgraded but none are showing in the upgrade process, help!?

Is there some hidden thing quest I need to do before advance?

I remembered this spreadsheet suddenly https://docs.google.com/spreadsheets/d/1HAwaYDPQpS8cxhVSG-oJyiMpTqxaRjUkYoeF2grKXgo/htmlview#
It seems Medical-grade plastics is supposed to unlock Chemical plant. But I do have medical-grade plastics but I can’t make chemical plant!

It seems I solved the chemical plant problem, I build another Medical-grade plastics in the same settlement as brewery and I was able to advance it.

I’ll see if I can now advance more but meanwhile hints are welcome!

Basically, stuff needs to be built in the same settlement. As you have figured out.

Yes I think I figured it out. I’m now getting them all I guess as I just use console to upgrade the plots and putting them in the same settlement as I can’t be asked to wait again to get them upgradable.. :D
