What seems to have happened

• She became less visible after her long TV run, which made it feel like she dropped off the map.

• She has continued to pop up in entertainment news, including reunion coverage and fan interest around her older roles.
[6][10]
• There was also a serious 2013 stalking case in which she got a restraining order against a man who threatened her and her husband.

Why people ask this

People usually ask this because Alyson Hannigan was everywhere during Buffy the Vampire Slayer, American Pie, and How I Met Your Mother, then seemed much less present afterward.

Latest public buzz

Recent coverage has mostly focused on nostalgia, reunions, and how well she still looks to fans rather than any major scandal or comeback drama.

TL;DR: Nothing major appears to have “happened” to Alyson Hannigan in the sense of a public crisis; she simply stepped out of the spotlight more after her biggest TV success, while still showing up occasionally in public and entertainment coverage.
