This happened to me a 2yrs ago with the original spamsnake. I was busting my brains trying to figure it out and did the same as you. I did make a mistake in my transport file, which I caught, and it was causing the problem. However, even after I fixed the entry and postmapped it, it didn't work. So I too did what you did, and it worked.
So congrats and have fun. Hope it works out for you.
