VINE, plant grows up the side of WOOD. INST wire is now also a battery and will charge if it doesn't give off a spark right away. Will give spark to NSCN or SWCH that is on. found some more wall defines i missed. moved wall code up 100 numbers. INVS, solid that turns invisible to elements when under pressure.
