I just bought Accele=Dracyan and started to put him together. Everything was going well until I heard a CRACK when I tried to screw in the studs. 3 out of the 5 studs that came with it broke. I was being careful, too! However, the studs seemed to be giving a lot more resistance than my other Cross Fight B-Daman (such as Twin=Drazeros and Rev=Dravise). Also, some studs had already fallen off of the tree right out of the box. Was mine a factory defect because the plastic was possibly weaker? I built One Sided=Sharks right after that and it went together just fine. So I don't know what the problem was. Is there a certain way to assemble these so that the studs don't break? Or was I just unlucky? Any help at all would be great! Thanks!
