@SimGuruMaaike This happened to me too. I just retired all 4 of my Sims yesterday. I definitely did receive the heirlooms because I sold them after I received the duplicate of each one. The only thing I did different this time is none of my Sims stayed around to do the mentoring...I just moved them out as soon as I retired each one. I have the same message for all 4 Sims. Maybe this will help you narrow it down. Hope it helps. 😊
EDIT * I wanted to let you know that @Simfanatic08 retired her Sims and moved them out without having them do the mentoring and she got the same message but did receive the heirlooms. However, @rmw8855 said she allowed her Sim to do the mentoring. I was hoping it was a message problem.

I haven't seen any new reports on this issue, so I'm closing it.
If you do see it again or still, please let me know so I can open it again.

Customer service never refunded my tickets since this issue first occurred, and I stopped playing the game because of it. Just FYI I spent over $300, and was not taken care of.
The level of care and concern shown by a customer service person constantly trying to close my support ticket after doing nothing has taught me to not ever play another EA title that involves a micro transactions, as they clearly do not honor purchases.
Good job EA
