Enemies not getting aggro'd

[Rick.B.61793]

For some reason, I've gotten a strange bug that makes it so enemies don't aggro onto me before I attack them. Whenever I get a random encounter and it has enemies in it, they just stand completely still and don't do anything, and if they're human, they'll cycle through all of their aggro dialogue without doing anything. It also happened with Geckos in the toxic cave and some guard dogs in the back of New Reno Arms. It's incredibly helpful but I really don't want to keep playing like this, and I can't find anything about it online.

Okay, I actually managed to fix it by just entering combat with a passive enemy, which in hindsight is a really obvious solution. I'll keep this up in case it happens to anyone else though
