Is there a simple script to activate a new Lifetime whish, After completing them? (Without touching the MC-Options).

Or maybe even activate a chance, that the Lifetime whish comes up in the normal „Whish List“. (Like it does when you are a Child, so there has to be a Gamecode. Maybe erase the Lifetime whish after completed automatically, and „fake“ the „Child-Status“ for the whish-System, so it show also the Lifetime whishes!

So you could Choose between 2-3 of them.

The hole thing would make the game much better and it would be a great motivation for a Long run to get all Lifetime whishes with 1 sim!

There is currently no way to accomplish this with NRaas mods, that I know of. Would you expect the same auto-generation of LTWs upon completion of one to apply to inactives (this would be a job for StoryProgression), or did you have actively being played sims in mind only?

Afraid there is almost no such thing as a "simple script" in the context of TS3. It's all pretty complex. Will have to leave it to our Developer to comment on the feasibility of such a feature request when he gets to this thread.
