Nah, wasn't the trade system or anything similar. Following some hardware changes there were some permission errors to adjust. Unixmad and I were working closely to get this resolved and it's all good now
There were some issues with the mall failing to check flags properly (z-z) and it caused some issues but we should be back to normal.
But yes, I'm not a fan of the killstreaks in place at the moment. We're working on a bunch of changes and I hope to be rolling them out pretty soon, however it will take time
