Hey!
I have a fresh install of the 13.04 nightly build (but issue persists for a while, on all beta & nightly versions of 2.0 I've installed since 2 months or so).
I do not see touch input blocks on the block editor. Below a screenshot (taken from example game, which is converted to mobile).
If I copy/paste blocks from other behavior, I think I can use them, but still, no way to access them normally...
I've been trying to solve it myself, reinstall stencyl, try different projects... nothing helps, I give up
