They will fix it, but the players will remain the same if you play a season or so. They can't fix it retroactively so if you're concerned about the development of your players I'd hold off on playing for more than a season(or at all) unless you want to get great mental attributes but bad technical ones.

Ah okay, thank you. 
 

So if I played one season, a player would only ‘miss’ one year of normal development or is that player permanently going to miss out on this patch?

So am I right in thinking we can get on with our main save and the fix will apply into it?
