Other mistake: When in the Mayan temple Flynn pools out the book. It is completely intact and the pages are flat and even. A book which has been under water for a long time (during their swim) would not look like that.

Factual error: When Flynn presses the stones at the Mayan temple, he identifies the numbers that are carved on them. The stones do have the bars and dots of the vigecimal Mayan numerical system. However, he identifies the specific numbers incorrectly. For example, the stone that he claims says 65 actually has 180 imprinted on it.
Flynn Carsen: I just want to get to know the Nicole beneath the surface arrogance. Peel back the layers.
Nicole Noone: What do you think is below the surface arrogance?
Flynn Carsen: More arrogance. And then perhaps a few delicious layers of flaky disdain. All around a creamy sweet center of homicidal rage.
