[1.3.3159 + DLCs] Sibling Relationships Disappear -Sibs Have Different Surnames

[Dewdrop]

1. Circumstances: When starting a new vanilla game, I started with a group of tribals, where one pair of siblings have the same last name, and the other pair have different last names. I know the family relationships disappearing bug has been reported before, but it seems this has been addressed to an extent. Because...

2. What happened: After a few minutes of playing, the sibling pair with different last names lost their relationship. However, the relationship was preserved for the brothers with the same last name.

3. Expected: That all sibling or other family relationships will be preserved for all of my colonists. It's sad they forget their brothers/sisters!

4. Steps we can follow: Start a new game with at least one pair of siblings with different last names. I tried twice, once modded, once vanilla, and saw the same thing happen both times.

I can attach a save if needed, but this bug is easily reproducible. Also would be happy to attach a log, but it's referencing all of the mods I had prior to starting the vanilla game, I'm not sure why. Let me know if you would like these! I would really love to have this bug addressed, losing your pawns' family relationships spoils the game for me. Thanks!

I recall this previously being mentioned and believe it is on the dev list. Here is the other post I found on this. https://ludeon.com/forums/index.php?topic=55261.msg491666#msg491666

Thanks for the bug report, and apologies for that issue.  I will add this to my bug report I've filed, it hasn't been resolved as of yet, but is on the list.
