No matter how a vampire is spawned, be it from the coffin at the start of a scenario or during a raid/caravan (tested, received powerful vampire message with no generation number, and vampirism was already gone) all vampires have their vampirism removed, and in the debug log, it states something about how the 3rd generation sire cannot be found.
I did many load order tests, and even with only Hugslist, Jecstools, Humanoid Aliens races 2.0, Modswitch, Prepare Carefully, and RoM Vampires installed, the issue is consistent.
