Patch is live and I am waiting to see if they "created" any new bugs. Happened last time with the last patch causing WD and a few other heroes to crash the game and cause people to abandon games. Should have seen the dota 2 dev forum and the amount of people who were extremely unhappy with that issue. Fingers crossed this time!
Edit:
Yup, serious bug. Don't get Tiny + Aghanim's Scepter before level 16 or you will disconnect and game ends for everyone. More at
