nope, no tech tree altering mods installed and I have no idea why its happening as, after uninstalling and then reinstalling the mod, the bits are still not available in either science mode or career mode. that and the bits from the mod for storing the modular storage items, the x2, inline and end are there, but not showing up in the tech tree for some strange reason and the same thing is happening to some of the umbra space industries, usi, parts where they are there in the sandbox save, but they don't show up in either science mode or career mode.
although I do have the community category kit mod, not sure if that would have anything to do with it though as well as community resource pack

ok, had manually deleted the mod folders in the ckan folder as well as on the gamedata folder and uninstalled all the mods, only reinstalling kerbal planetary base systems mod and when I looked in the science mode save, everything was in the tech tree, so not sure what happened. below is a list of mods I had installed as I think it might've been one of them, but not sure which though
