I've been playing around with Construct 2 at work (;D) and have made this small test:
dl.dropbox.com/u/45711709/test.capx
Click on any of the red circles, they should disappear and spawn 4 new "shockwaves" which in turn should then destroy any red circles they hit and those should then spawn 4 "shockwaves" again...
If i click on the first circle all is fine but when i click the second and the shockwaves hits the circle to the left of it for example it will only spawn 1 new shockwave for some reason :(
