Xur has Thorn upgrade this week. I had Thorn already, with some upgrades to it already. I selected upgrade and found that I now had a Thorn that was reset to base level. I read about the pre-DLC level 30 vs. post-DLC level 32 stats during the upgrade process, but since I did not even purchase the game itself until AFTER the DLC was released, this is not the case. To ensure it was not a 30/32 issue with my now reset to base Thorn, I upgraded it with Xur again. He took the materials again, but did NOT upgrade my Thorn for the second time. This is a serious bug Bungie, I want my materials back or my Thorn upgraded. What do I need to do?
