The majority of the episode is supposedly set in France. Toward the end, while in the cabin, Boris is seen cooking on a stove. On the wall next to the stove is an electrical outlet. The outlet shown is an American outlet, not French.
Near the beginning, when Bozer is paired up with Riley and Mac is paired up with Bozer's secret girlfriend Leanna, it would have been perfectly reasonable to point out that since Bozer is more familiar with Leanna than Mac is, and Mac is more familiar with Riley than Leanna, that switching those pairings up would make for far more believable couples. This suggestion could have easily been made without revealing Bozer's secret relationship, and would actually make strategic sense. Yet between 4 people who are all portrayed as having above average intelligence, 3 of which who knew about Bozer's relationship beforehand, none of them think of this, never mind suggesting it.
