Hello,

I can recreate this issue as well. I’ve tracked down the bug to the getColumn call in the library function randomBreed(). For some reason, it is intermittently failing to retrieve the list of names and returning a list of length 0. I don’t have any access to the getColumn() function though, so I’ll pass this one on to the code.org team to take a look at.

Thanks for pointing it out!
