This is really tiresome, in my 3rd playthrough Boone doesn't tell me anything that triggers Bitter Springs quest and I have done exactly like before, had him when wiping Nelson and Cottonwood Cove of Legion, have high NCR standing etc.
Last two times he talked after killing all legionnaires in Cottonwood Cove and that triggered the quest.

It really seems that by now "I Forgot to Remember to Forget" quest will not trigger...it is way overdue and nothing relating to Legion can happen anymore, also I exhausted every single dialog option with him.

Is there any way that you can trigger the quest via console? Has anyone else encountered this?

Damn bugs... :flamethrower:

And yes, there are over http://fallout.wikia.com/wiki/I_Forgot_to_Remember_to_Forget for sure.

At least your Boone isn't getting blown up by random missiles.

Confirming that the mission triggers for me (with the latest update and everything) because I played it yesterday. I went to the Legion Fort and wiped everyone out, and as we were coming out of Caesar's tent, he started talking to me about Bitter Springs.

Personally, I think it's a specific amount of hatred the Legion have for you, not the amount of time or progress you have with Boone as your companion.

Did you talk to manny about bitter springs?
