Cool, thanks for doing that research Rica. It makes sense they would be elders since that's sort of how their ageing works.
I didn't know Potent Cure Elixirs are only for age stuck werewolves, good thing I haven't used them for anything yet!
And only then if you've gotten the OK from Metro or myself. Remember that.
Can I assume that the family mausoleum works on the same principle as the family museum in an immortal dynasty? You can buy a lot for it, or you can have it on your home lot?
Yes this is true but remember if you do it off your home lot - you need to be careful that those items can stay where you put them. Meaning that no one in town will randomly pick up one of the potions, elixirs, etc.. Also remember if you're going to do it with sculptures, you have to have a sculpting station on the property or you won't be able to transport them. It would certainly be easier to have them on your lot especially since it's only 9 items per generation but it's not a restriction.
Note: If someone chooses to do the family mausoleum off lot and then has a game glitch where the only save would be to switch towns, you would either have to deal with the current town or fail due to being unable to take the family mausoleum with you because it was off your property. Placing any lot beyond your family home (if and only if you have permission to do that) is against the rules of Edit Town. So remember that when working on your strategies and back up plans.
