Right before everyone goes to sleep the first night, Barbara is talking to Ian, and her hair is styled with a bun in a hairnet and a fancy headband. In the next shot her hair is back to its normal style, even though there wouldn't have been enough time to take it down, nor do the hairnet or headband appear anywhere near her.
Barbara activated her travel band in the last episode only seconds before the others, but appears to have spent quite some time in Morphoton - changing clothes, picking out fabrics, etc.
Even though everyone in the room at the time is lying down, a shadow still briefly appears over Susan.
Before Ian lies down, a boom mic briefly appears over his head causing him to glance up.
