Workin for the weekend!
I've had this happen on a XT cassette with the 4 arm spider too.I think my friend did the same exact thing. He talks about it on his blog....

XTR carrier is totally different than XT. It is 2+2+2, white XT is 3+3. I recently had the two cassettes side by side and XTR seems to be designed to handle more torque. It is also built with better grade materials. I say it is definitely stronger than XT, besides being lighter. 3 times the price but 4 times the quality.Yes. I did the EXACT same thing this last winter. Same cassette, same spot...I'm even the exact same size. The XTR carrier would have to be made differently in that location to be stronger...I'm not sure on this detail.
Keep mashing, I say. I bought a couple spare cassettes on Ribble in case I do it again. They were extremely cheap...pay to play, I suppose.
