Well is changed to not shoot players in... well in a modpack which we both happen to play which shall remain nameless to avoid derailment.The sentry turret, or at least in 1.4.7 Ultimate, was configured to shoot at everything.
Including players.
This may be changed in other versions.
You'd have to ask Dave, as I don't have any spare nonhostile entities to test on.Quick query - are they configured to shoot all non-player entities?
Or all hostile mobs?
Really?
No pig spawners?
So all non-player entities..
Funny though - try an empty minecarts.
It's an entity, right?
In general we should test everything that's an entity, but an unusual one.
Minecarts are all that come to mind for some reason.
