AssertionError: assert len(genomeNodes) == 1

[Jome0169]

Hello,

I've been using progressive cactus to great effect, but recently hit an error as I increased the number of genomes I was analyzing. The error is as follows:

    [2021-03-18T15:49:28-0400] [MainThread] [I] [cactus.progressive.cactus_progressive] Sequences in progressive, 0.859673: ['oryza_sativa', 'setaria_virdis']

I'm unsure what could be generating this error as both genomes input into Cactus are formatted correctly. Any ideas would be greatly appreciated.
