Main Quest Bug Our Dreams Still Divided

[Firedrake445]

I’m running into a bug don’t know if anyone else is with this quest. When I get to the end and talk with Kostya I defeat him in a fight but then when I open the sluice gates nothing happens. The quest doesn’t tick off the optional marker and if I leave for the garden Solace Keep is destroyed. I reloaded a prior save but keep having the same issue. This is pretty game breaking as I want to save solace keep not have it destroyed before the end of the game.

Created an account just to post the same. Defeated Kostya and open the sluice gates but the quest doesn't update and if I leave for the garden Solace keep is destroyed. I also tried a few prior saves and ran into the same bug.

Basically at a standstill in play.

Exact same thing is happening to me. I've tried on PC through Game Pass and also on xCloud. I interact with the sluice gate control, it shows the animation of twisting the wheel and the physical gate raises up from the lava, but it does not complete the optional objective and the keep gets destroyed when I proceed. I'm paused until this gets fixed. I'll try on Xbox soon to see if it's broken on there as well.

Confirmed solution: you should have two autosaves called "Point of No Return." The earlier one is before you jump in the pool of water. From there you should be able to run back to Solace Keep, fast-travel to a camp and swap your party members. I switched to Marius and Kai, then went back into the Keep. The cut scene then played correctly. I've now seen five or six people say this all worked for them.

I can confirm, loading a save prior to jumping into the pool of water then traveling backwards and changing party members resolved it for me as well. Thank you!
