I'm trying to make a fluid reactor and have been following tutorials from the wiki.
However when I add components in my reactor such as heat vents I get "Cannot be used in fluid reactor, please cool down in EU reactor". Has something changed since the wiki tutorial was written? I've tried searching but havnt found anything on this as of yet.
I'm using industrialcraft-2-2.8.30-ex112 on 1.12.2
