center cap

Hello, I had quite some center cap pops recently on my Aolong V2, has anyone noticed it? And have someone a solution for it ?

If you have one or know of a place where I can find a replacement that would be great. I would really rather not buy a whole new puzzle and new tiles from cubesmith just because I'm missing a stupid center cap. I lost my cap in my girlfriend's car and we can't find it. She just cleaned out her...
