Instead of removing all those epilogue lines it would be so much easier and logical to just remove this post-Orin break up dialogue, quite literally can be done just with one simple tag.
At the end of the dialogue, there's no flags like ORI_State_PartneredWithMinthara = False and ORI_State_WasPartneredWithMinthara appearing anywhere. Those flags are the ones which set up the breakup you get with her when you sleep with Mizora. Them being missing means you do not actually breakup with her, so its clearly bugged or just half finished work.
Was told that this conversation is listed as a topical greeting in the game files, if you continue playing without interacting with Minthara for a while, you should get to a point where the dialogue is skipped altogether if anyone else feels like trying this out after Orin is killed.
I am still in Act 1 with a fresh new dark urge run as I'm curios to see if that matters anything so will give me a few days to reach to Act 3 again.
