I have 1.22 patch and the bug they said had gone is here again. Once i have finished the mission FREYA BE PRAISED, the diary show this mission as not complete, fuck, there is no way for finish the game completely, for one or another reason. I have played this amazing game since may 19 2015 unstopped, once and again, and i will be happy if one match will be ending without a bug. Thank you.
Bugs and all, this is the best game EVER. Please make the witcher 4, as soon as possible.

Did you get the chest in the water close to the dead horse? Seems that many times the marker doesn't show it - but your witcher sense will, if you are in the right area.

Yes, i got the chest but mission still active, it´s not the first time, but cdproject said this problem is solved with patch 1.22, clearly they did not proper check... maybe the next patch.
