Just got my set and I'm really pleased for the most part, but I was hoping you guys could advise me on how to fix a couple of issues. First, Dr. Crank won't connect with Heavy Labour. Everything is in the right place and I can get the clip to lock, but the posts aren't locking, and he's just sort of sitting there. A light breeze can knock him off... Then there's Madblender's head. It's loose. when I pull it up in robot it's really loose. Any help would be appreciated. Thanks.
