Had this bug before: A raid occurs and I get the notification that one raider is the sister of my colonist. After saving and reloading, the relation between them is gone. From reading on the steam forum, this relationship-vanishing seems to be a kinda common issue.
I am using a few QQL Mods. Loading the savegame without mods didn't change anything. All mods are 1.3 compatible.
The mods are
Auto-Cut Blight
Vanilla Expanded Framework
Common Sense
Blueprints
Colony Manager
Realistic Rooms Rewritten
JecsTools
TechAdvancing
Smart Speed
Harmony
HugsLib
