Please help me unaggro last light

I RPed myself into a corner and I am annoyed but determined. Please help if you can

So I'm on a single save run and got cocky after finishing HM on my first go. Went full RP on a barbarian with the full party mod and loving it.

I felt my character would get touchy at jaheira threatening me repeatedly after tying me up with magic so I clicked attack in response, thinking mol would come to save the day like usual. Did she fuck the entire camp aggroed. Not temp hostile either, nope all fully committed to my death.

The extra problem is as soon as the battle started the auto save for entering last light triggered and so now I'm stuck here.

I managed to use all my saved up invisibility potions to get the party out of there. Waited a bit and went back but nope all still fully hostile. Long rested and no change.

Things I've tried

I had entered act 2 through the drider ambush so I looped back round to the Jonas encounter. It triggered and I saved the harpers, went back to last light and still hostile.

I thought if I could trigger the thaniel quest by going to Oliver that might be a way round so I did that but no good, after I fought the shadows Oliver vanished and even though I passed the checks to see that Oliver was a something I couldn't tell halsin

Any other ideas? I'm on Xbox so couldn't do the save file thing either. The harpers got the damn lanetern so I don't know how else to proceed, please help I love this damn barbarian 😫
