If you do Abram's quests and free Maura, then later do the Protectorate quests, you encounter Maura in the Free Drones cell after gassing it. But she's not hostile. I was skirting around the mutagen clouds after clearing out all of the hostiles and found her standing around, oblivious to what was happening. I spoke to her and we shared an interesting conversation about her past and the Free Drones before I left her standing next to a mutagen cloud and exited the base. Bug, I assume?
