Hey Guys,
This is just an "info" post, but if anyone has the Asia Exclusive Generations 3 Pack Warriors (?) Kup and he's not transforming to bot mode properly (chest piece doesn't quite rotate the whole way) it turns out you're not alone.
I had the same issue with mine, and when comparing it to the original release I figured it was the chromed grill causing issues, but after reading information on the problem with the Botcon Hoist version of the mould, turns out it's exactly the same problem.
So I followed the instructions to fix the issue found
here and problem solved, so it turns out that factory issue on Hoist was not an isolated problem.
Hope this helps anyone else in the same boat.
