Plot hole: While breaking into the vault, Gabe and Ripley use a reciprocating saw to cut a block from the concrete wall. The block is several feet thick, quite beyond the reach of a saw of the sort. The view after the block is cut also shows no holes where they would have had to drill to get the cut started. (00:56:00)
Revealing mistake: While breaking into the vault Gabe and Ripley use two ratchets to pull the large block that they cut out of the wall. The block moves as they pull the ratchet arm back. The block however moves only at the end of the pull for the second pull which makes no sense. This was an obvious timing error from whatever was really doing the pulling. The ratchet itself would've only pulled the block an inch at best. Additionally, when the block is almost out it shifts unnaturally showing that it was not made out of concrete. (00:56:45)
Continuity mistake: The first time we see the zoom on the digital watch on Gabriel's arm in the vault, it's counting up the time. Next couple of times we see the watch, it counts down the time. (01:04:35 - 01:05:35)
