No Response Preston turning hostile

[Lystraeus]

As a companion, Preston turns hostile and [hates that] at the slightest stray shot.

Usually companions take a minor amount of damage before leaving.

I've tried removing the executioner perk with console, didn't fix the bug. (not sure how I got that either, I think a stray mortal settler lost a fight vs. a gunner).

I can confirm it's a bug with Conqueror. An awkward side-effect of meeting Jammer.

If you're intending to play peacefully, and get accosted by Jammer, you gain the optional quest to kill Preston et al. If you ignore it, join the Minutemen, the quest is still active. Problem is, if at any time you hit Preston in the slightest, he'll now turn hostile. Understandable if you headed into the Museum to kill them; not later when he's your follower.

Whilst the player can fix it by moving along Jammer's quest, a proper fix would be to fail the optional component when becoming General.
