Other mistake: Throughout the episode, Lucifer's car has a California license plate - but that is, just one. He is missing the one in the front. In the following episode the car does have the regular 2 plates, and when he is pulled over at the beginning (and keeps being around cops all the time), nobody raises an eyebrow at the violation of the code.

Other mistake: The dynamic of the scene with the paparazzi outside the party is quite absurd: forgetting the fact that the paparazzo just happened to have amazing parking privileges (the only sedan in the street, allowed somehow right by the red carpet!) the timing is all wrong, as he "just" made his escape a minute later, witnessed by Chloe walking away just then from the paparazzi brawl. She had walked past their lot already over 30 seconds before, while Lucifer stayed behind forcing the comical confession out of 'Friar Tuck'. (00:26:00 - 00:26:35)

Other mistake: We are shown several times the first person perspective of a paparazzi camera, with the HUD. From a diegetic point of view though, it is used in a way that lacks coherence. For instance, in the red carpet scene the photo count goes down by one every time the shutter clicks, while in the car scene it does not go down at all. And it really could not have been Josh's camera in the red carpet scene, because it photographed Chloe once he already escaped and from behind.

Other mistake: Despite the presence of multiple paparazzi on site while a civilian opens a police car, drags the main murder suspect out of it for some rough questioning and generally creates a suspicious scene, nothing about it leaks in the news (one guy even takes picture of the other side of the road!).
Other mistake: When Lucifer and Chloe are talking about the Player after-party, the same extra walks by twice (in the same direction without having enough time to double back). After Lucifer says "sex afterward" and it cuts back to Chloe the women is seen and then when Chloe walks away.
Answer: Yes and no. After the body dies, it loses about 1.5°C per hour until it reaches ambient temperature (i.e. the temperature where the body is found). But there are factors affecting the rate of loss, and one has to assume a starting temperature of 98.6°F. In this case, after factoring in the time from when the police were called to when the body temperature was checked, it would have been determined some time had passed, just not a lot, before Beth saw Moira standing over Megan. Really, what they were saying is Moira's story is believable: that she found her sister dead and picked up the hammer right as the garage door opened.
