This is very obvious in the modoc brahmin pasture. Your companions will just stand around like idiots while the dogs attack the brahmin, even if you are actively attacking the dogs. They will never attack the dogs till the dogs go hostile on you, which only happens when a few of the brahmin are killed. Another common scenario is when a critter doesnt notice you (e.g. too dark) and even though they are close by, your companions wont attack it till it notices you and go hostile. Is ther eany way to fix this? It is very frustrating for the modoc quest.
