Hi Jan (@janosch),
I had used the touch event's targetTouches property to implement your feature request, which contains information where you touch the surface with your fingers. So at touchStart this will contain coordinates, but not at touchEnd because then you don't touch the surface anymore.
By using the changedTouches property instead, it works much better. This contains at touchStart the same information, but at touchEnd it contains the coordinates of the touch points that have been removed ...
When you install the Github version again, it is hopefully solved now.
