I was just playing with a sample and it seems fairly accurate. Try pulling everything out except a couple test items and see if they work.
I have attached the test I did.
Hey thanks for the input! I actually just updated the version of Construct I was using, and turned Pixel Rounding on, and that seemed to fix it up. Not sure if it was the pixel rounding, or if something was a little wonky with the unstable version i was using. Thanks again!
