For some reason, I can't buy the LVT05 in the RnD (I'm assuming that LVT10 is the same story). After buying it and exiting RnD and entering VAB or reloading a save file, it still says that the part needs to be purchased. Also the attachment nodes are misplaced (with restock, idk how it is w/o it). It looks ok in the editor, but in flight the engines appear higher than they are supposed to.
