AOZ Studio V1 (TBD bugs clean/-> V2)

When I scale a bob, the detection isn't being detected. I've attached an example (with test bobs), but here is the code:

#manifest: "pc"
#displayWidth:1920
#displayHeight:1080
#fullScreen:true
#fps:false
#splashScreen:false
by=1
by2=10
do
  cls
  bob 1,10,by,1
  if mouse key=1 then bob scale 1,100,1:by2=80
  bob 2,by2,10,2
  if bob col(2) then locate 1,5:print "HIT"
  wait vbl
  inc by
  if by>100 then by=1
Loop

IMPORTANT! Press the mouse button to activate the scaling. When it first runs it detects the collisions, then when you press the mouse, it doesn't.
