Based on knowledge of the game I have now, I'm fairly confident the few xpac features are not going to cause issues for those who don't have the given pack, so I'm simplifying it to the one download. I know this is an inconvenience, but the traits were previously 64-bit, which causes issues with the new Open Sim Profile way of viewing a sim's info. This means any sims who have one of the traits will lose it and you'll have to re-add it in CAS.
