Warped parts is just a poor quality model. I wouldn't buy anymore of them. That Warhammer 40K shit is expensive from what I have seen. No way in hell would I deal with warped parts. I would send it back and get a refund. When you are paying $50 for some fucking plastic that shit better be right and of good quality. When it comes to just regular models warped parts is either seen as a defect or the sign of low/poor quality model making. Usually by some shitty cheap company. You would see this a lot in model kits from Eastern Europe.
Now I have heard cases of Dragon having warped parts cause they stuck them in the bag and in the box while they were still warm and they got warped. These people that had this happen to them got a new sprue of parts sent to them. I would call the place you bought the models from and request a new kit, a refund or contact the company that made the model and get a new set of pieces for it.
