For some reason the small cargo and 1.25m cargo bays will not unlock in the vab. I’ve researched and paid the entry fee in r&d yet it still is grayed out in the VAB. When moused over in vab, it states it requires an entry purchase in R&D but doesn’t have the green bar to pay it. When I return to the R&D building, the parts are duplicated, with one set purchased and one set requiring purchase. This continues no matter how many times I purchase, with more and more copies. I can remove the duplicates by deleting them from the save, but cannot find where they are tracking individual buy ins in the save to edit that. Does anyone either know how to fix this, or at least the save location so I can force it to recognize my buy in?
