YES!! I just had this happen to me. I put a new one in two weeks ago and low and behold I got home from the field last night and wanted to shoot off what paint I had left and it was puffing, so I removed the QEV and it was really soft, just put a new one in and whoosh, just like new, Thankfully it didnt break at the field during practice
