I'm playing Giana Sisters TD and have some problems in level 3-10. When Gurglewocky hit his rock to me I can see the rock. But when it stands still and I will push it to Gurglwocky I can't see it.
Sometimes one can see the stone, but very often he is simply invisible. Even if I jump then to the place at which the stone would have to be, nothing happens.
Can you help me?

after playing a while, I can say, there ist no bug in level 3-10.
I had used too much time around the small rock to stop, then he is invisible after some time.
Now after I have changed between the sweet and punk Giana, the stone remains visible.
I can stop the small rock and hit the dragon.
It was my mistake.
