[OPEN] [GTW] Alien wiped out wife's memory for no reason

No.  None of them have that.

Unfortunately, EA made the "Memory Erase" action a mischief action and not a mean action and sometimes it queues up improperly. The only vanilla fix I've found it to prevent it from autonomously taking over is to make sure alien Sims' mischief levels either stay at zero or one, and to avoid playful moodlets. You can cheat your alien Sim's mischief back down to one using "stats.set_skill_level major_mischief 1" or something along those lines. This is problematic since Sims will autonomously gain mischief skill with "troll forums", which tends to pop up for anyone who has a computer with a high fun score regardless of whether it makes in-game sense or not.

Both of the alien Sims I've played with long-term have autonomously attempted to memory wipe their spouses. I was able to catch the action in time for one and stop it (he was playful at the time), but didn't stop the other one since it seemed story-line appropriate (he was arguing with his wife). Both times the Sims had max friendship and max romantic relationships. For the successful attempt, the marriage was completely wiped out in addition to the relationship. This was before the traits update (a year ago), and neither Sim had the goofball trait - they were Romantic, Active, and Cheerful (one was a clone of the other, so same traits).

I think what would solve this would be if the team updated Aliens to have "Memory Erase" be mean instead of mischief, especially now that with the traits update goofball Sims are autonomously using mischief actions. A memory wipe isn't a prank, it's an attack.

I "fixed" it by exiting without saving, loading that same save, and going on the date again.  Luckily, the wife had no "dazed" moodlet and remembered her husband.  I must add that the wife originally got the "dazed" moodlet after the venue I had sent them to had loaded.  Before that, there was nothing.

Once the alien's identity is known by the target sim they'll autonomously erase the target sim's memory of them. They'll even do it to other aliens. The only way to stop this from happening all together is a mod or you could watch every interaction your alien is about to do autonomously with his wife.

@onemorekayaker I agree with you on the social being an attack and not a prank.

For real though they need to get rid of “memory erase” as a mischief interaction because it’s very annoying. They’ll memory erase out of no where when talking to a good friend. Fair warning don’t make a goofball alien because your chances of memory erase are higher after the recent trait update. They use mischief way too much.

Just here to anecdotally confirm that goofball aliens are worse. This one's done it to her wife twice in one game session. -_-  

Edited to add: Other suggestion with this--can we not erase their freaking marriages??? Make it a mean thing and not erase the marriage. 

Editing again to add some more: She just did it again, and I'm cheating her mischief back to nothing. Three times in one sitting is a bit much.

I just had this happen too.. 

You can disable the "Erase Memory" autonomous action by using MCCC.

MC Command Center (deaderpool-mccc.com)

I disabled it by triggering the action with a big distance between the 2 sims, and disabled it using the currently running scan feature in MCCC.

I would like to add that I had an alien sim memory erase one of her friends and she was a proper sim! She had no goofball trait. She's proper, neat and a cat lover. She was not playful at the time. Proper sims need an update that they never use mischief autonomously. She seems to use it all the time. I have updated her with the "dislikes mischief" property in CAS and hopefully that stops her from doing it again.
