Hey all, I am totally new here and looking for some help. I got 42055 for xmas from my wife and have completed the set but seem to have a problem with the bucket wheel sticking. You can see an example of the problem here (not my video) I've tried the fix in the video and this didn't work. I'm wondering if anyone else has had the same problem and knows how to fix it? I'm not great at fault finding with lego yet! This is the first model I've built in 15-20 years. Thank you.
