bam2egg error

I’m trying to edit a toontown model (phase_3/models/char/tt_a_chr_dgl_shorts_head_1000.bam) so I’m trying to convert it to the .obj format. This model, for those who don’t know, is supposed to be one of the dog heads. However, when I use bam2egg, the model goes from being a full dog head to being dog ears. Any clue what’s happening during bam2egg that’s causing this?
