i have a replay of recluse running into enemies.. ill check i was not mistaken but from memory its this replay
https://zero-k.info/Battles/Detail/771272ok ill check it now....
yeah @ just after 11:52 @ +51% a recluse stands still and allows itself to die
it seems to be when its doing its firing animation and reloading animation.. even though it could be running away and shooting it will finish attacking or reloading on occasion
ad just after 17:00 i loose a recluse who stands next to a lotus.. maybe it cant retreat when its got units baring down on it from 2 directions
as you ca see the recluse might also just be targeting units they consider a safe distance while they ignore the closer units
