if you have changed the layout or rotate the towers, could you test it again without changing anything in the lay out for me?
When you test the capx, take a closer look at the tower where the purple arrow is pointing to.
That tower will reach to zero health, but the grey bullets are passing through it instead of destroying it.
Where the cyan arrow is pointing to has some issue too. That tower went to -1 health. The bullets are overlaping the tower instead of destroying it.
Those are the problems =/
