i found S.A.W. mechs quite a few times and if i get it back/get back to the ship it's to big to go anywhere but the teleport to sureface area in the first ship, in the gryphon it can move a bit more free but still not through the whole ship and in the titan it's even stuck in in the teleport to surface area, i would love to have it able to move around freely like my normal units in all the ships since it's a pretty handy and powerful unit to have walking around in your ship if the enemy attacks or you denien to pay 1000 oz, and i think it will also happen if you get units the same size as the S.A.W. mech
