Ok Grinder is doing my head in. To people who have it, when I'm pulling out the tail from the inside the legs to transform to Dino mode, it gets caught on the bottom bit of plastic. I was able to pull out the tail from the left leg last night but noticed now that I've taken off a little bit of chrome on the end edge of the largest tail piece. The same thing will happen with the right leg so I haven't forced that one.

Is this an issue that anyone else has had? Mine doesn't appear to be misassembled, it just looks like there is no clearance.
