I was unable to find the original topic talking about this, but I’m pretty sure it’s still relevant:
When selecting for player 1 “Boss” and user-selected algorithms have a large chance of failing on turn 0, which really sucks since I like to debug faster than that.
After some random doing of stuff, I’ve found a way that reliably works regardless of this:
Set player 2 to “By Hand”.
Then, all you have to do is “Submit Turn” to figure out if your algo is working correctly.
