I've re-installed and tried with no extra mods, but normally I'll use MJ, Kerbal Joint Reinforcement, Procedural Fairings and Procedural Wings. The parts from the other mods appear on the tech tree . Brand new save with .90. I got to 4th node completely unlocked on the tech tree. Before on .25 the parts started on the 1st node so has that been reworked so they appear much later than the 4th node? edit... Well I feel a bit slow.... all the parts have been moved to later places in the tech tree. Thanks for the help!
