The only hiccup was a problem with the repair system, which DG has acknowledged and are currently hotfixing as we speak. The changes to itemization necessitated that rare weapons were more costly to repair, but something got fudged in the implementation, and when players logged back in post-patch, they found that the item health on their equipment was much lower than it was pre-patch, and that things were prohibitively expensive to fix. As of 4:30 EST, they pulled down the servers to fix this problem. The update on the website says that players that logged in before this fix will receive a "credit bonus" to compensate. We'll see what that means when the game comes back up in a little bit.
