Continuity mistake: When Krennic is first talking with Galen Erso on his home planet, the coat that Galen is wearing is visibly drenched, presumably from rain water, but later in the scene, when Lyra Erso intervenes, the dampness on his coat is now much lighter. (00:03:30 - 00:05:10)

Suggested correction: We know from Episode IV that some fabrics in the Star Wars canon dry very quickly, see the garbage compactor aftermath. This is totally possible.
I'm not sure if this is a viable explanation. While some aspects of life in the Star Wars universe are somewhat fantastical (the ways of the Jedi for example), this universe still follows the same basic psychics of Earth, so for example, something like gravity or the speed at which something dries would still be the same. (As for your Episode IV reference, I'm not sure if that counts as a defence, or is just a mistake in of itself).
