I know its in at least v1.1.1 as I have seen another youtuber, Anesos, with an electric gas covered portal and he is on v1.1.1 I think. Look up the gas collector, pump, and tank and gas pipes. I think they can deal with it but I have yet to get far enough to try that!
Thanks, I'll look into that and see what I can come up with dealing the invader portal. However, I must go back and diffuse these people who still think you can destroy the portal with a bucket of water like its a walk in a park.
