  Unfortunately player can't detect this error yet. I think, Zero division error(NaN, inf,-1.#IND) causes this error.
  You should check your code in onEnterFrame function. Notice If you give a Nan force value to applyFoce, All sprites and shapes disappear from the stage/scene. @atilim and @ar2rsawseen can you fix this debug issue? If I'm wrong, please correct me

  function game:onEnterFrame(event) -- do the low-pass filtering fdt = event.deltaTime * lowfilter + fdt * (1 - lowfilter) world:step(fdt, 9, 3)   for body,sprite in pairs(actors1) do if body.type == "ball" then if body then local bx, by = body:getPosition() sprite:setPosition(bx, by) sprite:setRotation(body:getAngle() * 180 / math.pi) end end end   if self.ball1 then ballx, bally = self.ball1.body:getPosition()   -- check your force calculation! --... --local force = accel*mass --local forcex = velx/curVel * force -- Sometimes calculation may be overlooked with zero value --...   forcex = 1/0 -- it causes "divide by zero error" forcey = 3 self.ball1.body:applyForce(forcex, forcey, ballx, bally) --> All sprites and shapes disappear from the stage/scene end end
