When Quinn and Campbell meet "Not Mr. Huang" in the abandoned warehouse, Quinn takes cover behind a white support beam when fired upon.
In the first close-up of Quinn we clearly see three bullet holes in the support beam.
The next cut-scene with Quinn reveals that the three bullet holes have disappeared, and instead been replaced with one bullet hole on the side of the beam.
In the last close-up of Quinn, the three bullet holes have reappeared.
