Emily, Customer ServiceThanks for your review. Sounds like something might be just a bit out of place. The best thing to do is double-check your build. Sometimes there may be a piece just a little off from where it should be, which can cause things to not line up as they should. You’ll also want to make sure that all the pieces are pressed tightly together (except gears, which need some room to turn). If you'd like a hand troubleshooting the build, give us a shout at LEGO.build/Service-BV.
