I'm not sure how Nanomad feels on this, but this thread is for testing the public pre-Alpha 2, not a privately compiled build. Posting bugs on own-compiled things is sort of irrelevant when the current pre-alpha has been released. I would think a better way of discussing the current changes to ML would be through PM or on the IRC.
Also, it's worth noting that having props disabled, which enables all the stuff in ML, is potentially dangerous as that's mainly where the bugs haven't been ironed out.
