i bet you have some funky loading issues w/ that wall causing that problem //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
I think it was a compounded problem. Something went wrong. Omega V2 will have a different dustcap, but since only 1 of your 15"s had this issue I'm going to say some of the problem may be there..
