What's the first build that started having the problem, and the last build that worked?

You can find this by trying a few builds, just go by halves. For example, if it worked in v1.0.0, and stopped working in v.1.1.1, just go halfway in between, and keep going halfway until you find it. I don't have the game, so I would have to pour through thousands of changes to try to guess what maybe could've possibly caused the problem. But you with the game can try ~10 times and narrow that down for me to 10 or less changes to look at.
