Just a heads up for anyone grabbing this set: I ran into a bit of a snag. My kit came with a long yellow piece (Size 5 axle/link) instead of the short Size 3 yellow axle needed for the build. I double-checked all the bags and it’s definitely a packing swap. If you’re starting this one, check your yellow axles early so you don't get stuck halfway through like I did! Luckily LEGO support is sending the replacement, but it still kills the momentum. Has anyone else seen this lately? submitted...
