The developers have confirmed that there is a serious bug in the DLC
which is certain circumstances will reset your character to zero and/or
delete your save. It appears if you co-op and then play solo your save
will be gone. They are working on a fix.

Also crimes on/off has been removed meaning that you can't freely choose
to have baddies roaming about. You can reset gangs which puts all the
baddies and bosses back but the only way to get rid of them again is to
complete the game all over again!

I haven't fallen foul of either of these luckily and have enjoyed Street
Racing and car impounding in solo modes only.
