TakaraTomy have issued a recall and replacement of Transformers GO! Jinbu due to a factory mis-assembly of the thighs. This mis-assembly causes the knees to not be able to bend the correct way and therefore, the combined modes arms do not bend the correct way either. Unsold stock has been recalled and customers (in Japan) who purchased the figure can return it for a correctly assembled replacement which will be available from mid-July.If one chooses not to return their figure, the error can be corrected by disassembling and reassembling the figure but there is the risk of misplacing parts like springs etc.
There is a picture attached for those who need to reference and check any figures they have in hand currently.
