I don't really know what triggered it, but I can't build anything or move forward past this point. I forgot to mention it in the video, but I can't build anything either. The game thinks I don't have any resources, not even bricks. I don't remember what happened with the crash in my first playthrough, only that while I was playing I got a crash log and the game stopped. But since I was still able to move around and show the glitch off with this one, I wanted to show what my island looked like, what was built, what was happening, etc to help with a fix.
I have also run into the water-walking glitch mentioned elsewhere on the forum, but only in my first playthrough. In the second one, it didn't happen.
Additionally, when resources spawn on top of the hammer-smashy-buttons, they can't be mined with the pickaxe. This was consistent through both playthroughs (berry bush the first time and coal the second) but was only mildly irritating, not game-breaking.
Like I said in the video, I really like this game so I hope this is of some use.
