The new patch for Phenomenon 32 should fix the rare “falling through the ground” problem (I hope) and the issue where one of the late research fields made another disappear. The save games should also be compatible.
Get it here. It’s 37MB. The new installer will be up tomorrow morning, and then I think we’re pretty close to a final version.
Edit: the (extremely) rare bug is still there, but the research issue is fixed.
