I've just moved the current Staging branch to p17_debug[for_modders]
This branch is a full debug build, with symbols - it's HIGHLY recommended you ensure your mods still work with the UI changes. NGUI, stupidly, decided to break its API - I've put as much ducttape in as I can, but there may still be issues. The debug build will help you track down issues far easier than the release build.
For the rest of you intrepid testers - I'm in the process of creating non-debug (aka high framerate) versions of all platforms now, for a final bout of testing!
