Scientist guards not attacking Murderers

So whenver a crate spawns it seems to work fine. They attack players, push and that. However, if there happens to be a murderer close by. That murderer can freely run among the scientists and kill them. The scientist simply won't shot back. They try to run away but give it enough time and one murderer can plow through all the guards.

How do I solve this? The regular scientists spawning at junkpiles attack murderers just fine. Its only the guards at the crate that refuse to shot the undead.
