https://weibo.com/6199528366/KB4y7nHZ6which they explain that the change in materials was due to feedback about stress marks in the first set. However the first set used a mix of Nylon and ABS parts so there weren't any reports about stress marks. Rather the common complaint was the color mismatch between Wildrider's Nylon and ABS parts, and that is the more likely reason for the change to full ABS parts.
I think the thing with Dragstrip was more about bad tolerances and not about missing parts that pic suggests.
