Weird! Can you remember what actions you were doing? That's pretty early on so it should be easy to replicate if you can. There are some ranges being used at 29 and 30. I had them overlap in case that might be the cause? The range would never be false but it's the only thing I can see that would possible stop them from spawning. I'll post in the update blog when it's implemented. :)
39 goes with the range as well. Hopefully overlapping the values will prevent it. I have yet to see it and others that I have shared the game with haven’t either but this is why a larger community is important :). Thanks for the info. I’m doing some clean up and adding a ‘boss’ and will include this with that release.
