When this code is typed into the terminal

lock vec1 to facing:vector.
set vec to facing:vector.
lock offset to vec:direction * v(0, -10, 0).
set vec1:start to offset.

kOS will throw the error "KOSDelegate.InsertPreBoundArgs: Stack arg bottom missing" when it should be throwing "Suffix start not found on object".

This only occurs when the code is manually typed into the terminal when the code is executed from a file it throws the expected suffix not found error.
