Hi, I had a question concerning the tech tree. I use procedural parts and the fuel tanks have size upgrades along the tech tree, however the 85kL upgrade is in a later node than it is supposed to be (an upgrade node of microgee fabrication instead of high performance fuel systems), I have checked the procdural parts and TETRIX tree mod files and there seems to be no indication as to why it's not in the correct node (In the procedural file it is correctly placed in high performance fuel systems). Help would be appreciated.
