I have encountered an issue with Touch object. It appears to be rather inconsistent in a certain case, though I can't seem to figure out why.

I am using Construct 2 r107, 64-bit on Windows 8 Release Preview. Tested in Firefox and Chrome, the issue is observed on both.
The issue is that when touching the three right sprites ("fraction"), the On object touched event rarely fires if at all. There are some very specific spots that trigger the event when touched, even then they appear to be inconsistent.
The left set of sprites ("animal" fire the touch trigger normally, there is no issue with them.
