When Rojas pulls up video from the tourist Instagram, and they see Charlotte passing by the camera. However Ruzek starts following the hooded guy, and then you can see the girls posing for the "great night out with my girls". Continuity error.
When Jay knocks out the "stained glass window" with his rifle butt, the "glass" peels away (obviously plastic), and the sound of the "breaking glass" is unsynchronized.
According to dialog throughout, this takes place in late March and early April, yet COVID-19 isn't mentioned at all, and none of the characters in the episode are social distancing or taking any other precautions. But of course that's because it wasn't filmed in March/April. It was filmed before that.
