I have started a new game and spent 11 hours on it today only to get stuck on a constant home screen crash when re entering the animus, basically after you get on the boat with sigurd and sail off, you get to step out of the animus, on several occasions I have tried not talking/interacting with everything and also talking and interacting before getting back into the animus. ALL of which has failed to progress, I have even cleared cache, unplugged hard drives and also loading previous saves. Every time you get back in the animus, it shows loading screen, it shows the icon in bottom right corner, then after about 45 seconds it home screens me. There is only 1 day left for the event and I think its a bit rude that the last update has broken my game. I am not uninstalling and reinstalling a over 70gb game, im not made of money and this type of thing never EVER works!! It is also a digital copy so the thought of corrupt files is a little bit facetious dont you think? 
Furthermore I can't even submit a ticket as soon as I select any , the option to submit ticket disappeared and live chat won't work.....typicalt!!!
