I also can't get any health options to work within my career. Haven't tried them in exhibition nor tried any other options yet.
for these problems we will need:
1) savegames
2) know where to put the savegames
3) a setup or match and situation in the savegame that repeatably crashes the game or causes the problem and instructions how to set it up and make the crash or problem happen.
4) if there is too many problems, we may just leave the options that affect buddies and AI out and stick with player only.
I am not playing 3 hours of career to find that it happens when you take on hacksaw Jim Duggan in the promo match and etc.
best,
Cal
