Thank you

Hi guys, I have recently installed this mod and everything working fine. I have seen a few older videos on youtube where people unlock mass extractor T2 and T3 via research tree and then are able to build T2 mass extractors directly or click the mass extractor and click click an upgrade icon on the far bottom left side of the screen. I have unlocked the upgrade options in a few matches now but I can not see the upgrade icon or see a T2 or T3 mass extractor to be built by the ACU or engineer. I am assuming the latest version of revamp or recently has removed these mass extractors? But left the research icons in place?
Thanks for any help!
