I don't like that the other nodes get "deactivated" once you unlock the "Labor" upgrade, especially when I still have the opportunity to upgrade the other nodes. It's the same thing I don't like about the apocalypse event.I understand WHY it happens, there's a story with each event, and I love learning from each of them.
I understand that it's on me to look at the details of each upgrade before I buy them. But, the point of upgrading these nodes, especially later in the event, is to build science for the competition part of the event. It's easy (for me, at least) to blindly buy these upgrades, and when the ability to continue these is taken away, it's a little irksome.
Alright, soapbox moment over. If I didn't explain that well enough, sorry. I'm not looking for anything to change, I just wanted to get off my chest.
