Ugh.... and this will strike in the June 2nd patch, regardless of getting the EP or not? Absolutely no escape then?
I'm doing a little programming, not games though, but I think that if they add those codes into a "code slot" that already exists, it might be possible to say "all items not having the new code will have code="0". No effect. I'm sure they could (and should) have done it that way, because the game is actually 5 years old and simmers have lots of CC that will never be upgraded by the creator. Crossing fingers, but hoping a guru can enlighten us a bit....
