Hi. I tried it , and it messed up my game play very bad. Bree got renamed to my male mc name and after some time you can't save the progress in the game , it got's an error.
But it could be pretty good if it got fixed.
I know a bug that really looks like yours. I don't think It's a bug from the cheat mod. I think you misunderstood what happened. When you start a game you can choose between Bree and Mike (Female or Male main character). If you choose the female path, you will edit Bree's name. If you choose the male path, you will edit Mike's name. All your save will show the name you put here.
Here is the tips to fix your problem: Make a New Game, choose Bree to be your MC. Call yourself "Bree" (First Name) "Cheese" (Last Name). Continue this game until the game leave you in the livingroom (You can skip all dialogue and choose anything when asked for something). Now return to the main menu without saving, and Bree should have her name back to normal when you load your saves ! (If you play Bree and want Mike to get back his real name, just do the same thing but with Mike ! ("Mike" (First Name) "Seeker" (Last Name))
If Bree (Or Mike) have her name fixed in her biography but not for her "interlocutor name" during dialogue, load your file where you wanted to get Bree (Or Mike) fix and save in a new location. Then quit the game and reopen it. When you will load your save everything will be fixed (Name in bio and in the "interlocutor name")
But now, for the error you encounter I don't have any idea, but maybe try "Ignore" when it happen. The game should run with no bug (outside the base game bugs).
I hope I was understandable enough and that I managed to help you !
