GMs: "Thank you for letting us know of a potential issue. Lucotte can't use the word master because that's offensive. She will now say Handler instead. Thank you for letting us know pso2 community! Keep letting us know about any potential issues!"
Segac's stance is pretty clear. I don't think any censorship has been reverted, but has been applied by default, added randomly for "reasons", or added when the community said something. I really hope Lucotte's actual voice lines has master in them, cause then it would be unlikely changed.
Lucotte's voice lines were probably dubbed a long long time ago so here's hoping.
