I'm bound to believe this might actually be few separate bugs which have the same symptoms but rather different causes, so while some fix suggestions might be myths, there is also rather varied ones which work for different people, debending of the cause in question.

False alarm. Bug remains.

Walked to Vault 101 lot (inside fence), checked stats, all good. Fast travel to Ten Pines. Check stats. Glitched.

Might be totally random after all.
