[RL] Sims changes Dynasties/Constant message after loading

I'm experiencing two annoying bugs after the latest update that directly affect Dynasty gameplay.

First, I'm constantly getting the message "(Sim's Name) has just joined the (Dynasty Name) Dynasty." So far, I've only encountered this with one Sim (always the same one) in the same Dynasty they've belonged to since birth (birth occurred before the May 12th update).

Second, I'm receiving constant phone calls from the regent of an allied Dynasty threatening to break the alliance if I don't try to bridge the gap. This is immediately followed by a second call from the same Sim telling me to forget about the problem. This cycle repeats continuously.

Hi there, your first issue seems like this report here - [RL] Sims changes Dynasties/Constant message after loading | EA Forums - 13401358

Same problem for me, as well. 

I have the same issue, I have mccc updated and tried the vanilla to see if it kept happening and it did. I don't want to make a new legacy though. After the 12 may update all my dynasty's broke 

Same problem :/ EA fix this!

I've been having the second problem (dynasty calls to patch things up) from before this update, possibly since the previous update.

Same here. I have no cc or mods. My dynasties are changing constantly and without my input. Disappointed because I lost the Alto dynasty because he passed and it moved his minor boys and their mother into her maternal dynasty. Very frustrating that the updates keep breaking the legacy/tree. I don’t want to start over AGAIN. 

The bug is persistent; even when the dynasty is stable, affiliations are constantly changing. All members of the dynasty switch to their father's dynasty, regardless of their family ties.

I have the same problem. Children that had left their original dynasty to start their own or married into another, was being forced back to their mothers dynasty every time i traveled to a different lot. Some were even part of 3 dynasties at once. Leaving or kicking someone out did not help, nor disolving and remaking the dynasty. Once born into a dynasty you're basically forced to stay in it. Game is unplayable for me till this is fixed. 

I have something similiar, everytime I open game it shows my sims joined dynasty. But they are in dynasty since they were born or they married years before. Right now my sim who is leader of the Thebe dynasty appears in different dynasty as memeber while he is still head of his dynasty (but I can´t see it from his POV, there is just the new dynasty he joined, but from POV of his wife he is leader of the dynasty he should be in)
