Arbiter of divinity won't unlock any map (so no atlas point)

The quest line worked fine, my first arbiter of divinity kill unlocked a full part of the citadelle and give me the corresponding point but after i farm the origin part to kill him again and continue unlock my atlas it did not work anymore, i did it twice (spending valuable origin part) but the only thing it does when clicking an ancient mechanism is activating a wall tower.

I don't want to do hundreds of maps FFS unlocking point 1by1 i'm losing it with all the dam bug :X Losing my time and currency just to face bug after bug after bug...

Edit: i let the post so it may help some one and you can blame me for being dumb. The atlas point unlock when you clic on the wall tower. my bad i guess
