Couldn't find a bug section, so I guess I'll post it here and hope it gets seen.
Weird glitch with Ohtani. I'm playing in Showdown, and if he's set to be just my DH, I can move him up and down the lineup as I want, but when he's listed in both my lineup & starting rotation, I can't move his spot in the lineup. Taking him out of the rotation and having someone else DH and I can move that DH spot too.
