Hopefully they issue a press release ASAP - this sounds serious.
Played a few more games last night with my franchise file started before either patch and almost caught up to current day... no freezes. Simmed ahead (but didn't save) and no issues people have mentioned.
It may just be a small group that are having issues. I'm only seeing people who have issues looking for help - not the guys who don't chiming in and saying all is well.
