Vampire Run

Far as I can tell, the VampireRun walkstyle is somehow hard-coded to having the Vampire Trait. Can't seem to track down in what way though. I figured maybe it's to do with the default vampire walkstyle, that they have a slightly different one on a technical level and that impacts it... but can't find any references to such a thing. I tried giving a sim the isVampire trait_asm_param, see if that makes any difference, but nothing.

Seems like the only way to get the walkstyle to work is for the sim to have the trait_OccultVampire_Manifested. Keep in mind I tried it with a custom version of Vampiric Run and it worked when the sim had trait_OccultVampire_Manifested, but didn't make a difference to their walkstyle otherwise. So I know it's not a bug with my custom Vampiric Run. It's gotta be something else.
