Dissappearance of 17 or 18 Settlements?? Help Please

[Ollorin]

Could anyone shed some light on why all but my newest settlement disappeared from yesterday to today? They weren't conquered by another house or faction they are all simply back to their original new village charter state. Almost a years work out the window and I'm just trying to understand before I chuck playing this game for good.

Thank you ahead of time for any insight or guidance that might be offered.
