no response is good, that means RB is handling it for TruePVE as it should.
here are possible reasons the damage would be blocked, if configured to do so.
Player Damage To Base Multipliers in the profiles if Heat is set to 0. this is not 0 by default. it is 1.0 which is normal damage. this cannot be it if initial damage works then stops
Entities Not Allowed To Be Damaged in the profiles - if it were configured to block damage to autoturret and boxes. this is not configured by default, so again I doubt this is the cause.
if the event is loading and has not yet stated "event opened" then ALL damage is blocked. again, you said partial damage was allowed so this cannot be it.
if the initiator and the victim were an autoturret/box then all damage is blocked. a plugin would have to cause this for this to happen, so it should not be the cause either.
if Eco Raiding has Enabled set to true in the profile
if you are mounted and have Block Mounted Damage To Bases And Players enabled in the config
if you outside of the event and Block Damage Outside Of The Dome To Bases Inside is enabled in the config
if you are not ally (team/friend/clan) of the owner of the raid.
if you have an active Player Lockout from the config
Boxes Are Invulnerable Until Cupboard Is Destroyed in config
Boxes Are Invulnerable in config
those would be the only reasons damage would be blocked to turrets or boxes, and most of that would block damage to everything.
