Can't place Thermal Plant
So, I was trying to find a good spot for my thermal plants and the one close to my base (where some sea monkey nests are) has no temperature at all.
So I found this one below the Delta Station Dock that has like 200°C when it erupts. Yet I can't place the thermal plants anywhere close to it. I even checked online and found pictures with the plants pretty much directly on the rim of the vent but in my game, it stays red and I only see the yellow outline of the vent rim.
Am I doing something wrong or did they change it so you can't build them on top of the vents anymore?
