So. ‘Twas all a mix-up. The previous patch did actually fix the “falling through the ground” problem. In an odd turn of events, I have since then updated the patch with a different approach to solving the problem that had already been solved.
I don’t know about you, but I think this is hilarious. I’m grinning like a loon.
Anyway, now I just need to decide whether to keep this new approach in the code or not, and then I can upload a pretty-much-final version.
Ah, the madness of game development…
