This is very helpful, I'm probably using an old save from Build 167, I'm not sure, but because I've been playing across multiple months that would not surprise me. I don't mind just restarting the game for that.
The only thing is, yes I was able to immediately replicate the content warning settings resetting themselves to low within a few turns. I checked every turn, and they seemed to shut off at the end of an encounter/scene. The specific scene was leaving Metris-2 after talking the gang leader into helping in the war, where there's some kind of traitor who gets caught and turned back into the leader. Once I was back on the bridge of my ship, the setting had changed from high back to low. I set it back to high after that, and went around the ship, slept, initiated some sex scenes, talked to crew members, went in and out of the bridge, and the setting stayed on high that entire time. It also stayed high when I went back to Metris-2 and interacted with several NPCs. I don't really know what specifically is causing it, maybe NON-repeatable/plot relevant scenes? But I do know it shuts itself off regularly for me, so it's not just that one exiting Metris-2 scene, but that's the only one that managed to trigger it for me in the few minutes of running around and checking.
