We're working on the issues you all have been experiencing on live since the update. Couple things..
You will see a small client patch go live pretty soon. This is only a speculative fix for a portion of the D-sync(invis) issues. It's being worked out at a much deeper level internally.
You will see Test server get an update this afternoon. We're hoping to address the Arrows and IDE's at bare minimum with this. We're just not waiting for EVERYTHING to be fixed before publishing. Would rather get these out to you incrementally over a couple publishes.
Storage containers, exploits and other smaller issues are being looked at as I type also.
