What is the butterfly effect? It’s a concept from chaos theory: in complex systems, even a tiny event can have unpredictable and huge consequences—somewhere else, at a different time.
All of Pathologic 3 is about that effect: we plastered the whole game with butterflies and moths—visually and logically. And where did that lead us? To the notes for Update #4, where we list some of the logical errors, inconsistencies, and loose ends we’ve fixed.
We promise we won’t make any more games about events with consequences: the studio’s next game will be a hockey simulator.
Below are the key changes in this patch.
Key Changes
(Most important) Fixed the kids at the Polyhedron who could remain there even after we had already led them out earlier. For the fix to work properly, you need to restart the quest.
(Important) Fixed nodes in Capella’s branch in the Cursed Inquisitor quest on Day 10. Players whose nodes disappeared in this quest will need to restore them manually via the console: set_global_variable Day10_Q10_5_MM_Earth true and then reset the quest.
(Fairly important) Fixed an outcome in Isidor’s funeral quest where players could end up with no final node to reset the quest. If you ran into this issue before the update, you’ll need to grant the final node via the console: set_global_variable Day2_Q5.1_MM_BuriedSecrets true
Fixed a UI bug when opening the Emergency Command at the end of the day.
Added a sound cue to the time-traveling UI—it was getting a bit too quiet.
The flying kids in the Polyhedron have been brought to order and now behave as they should.
Fixed odd behavior of the marker in Shekhen in Vlad the Younger’s quest on Day 8.
Moved Georgiy away from the Water Tower location once he no longer needed to be there. Also fixed the map marker behavior when resetting this quest and addressed issues on the location itself near the Water Tower.
The Cathedral Caretaker no longer repeats the euthanasia dialogue (even though the topic clearly concerns him deeply).
On Day 11, the child’s bone and hooks are now removed correctly in the Rat Prophet quest.
Lara’s petition for Rubin quest now correctly applies its consequences on Day 6 and Day 7.
Fixed an erroneous auto-reset of the quest where you talk to Artemy Burakh after the funeral on Day 2.
Fixed scrolling in the Settings window under the “Other” tab.
When opening the Notes tab, it now automatically selects the note you just interacted with.
Fixed the ability to put drugs from crafting recipes into your inventory. What it did before was absolutely unlawful.
Updated the euthanasia interface (hopefully making it easier to use).
Improved the tutorial shown the first time you open the euthanasia window.
Fixed studying Rubin’s vaccine on Day 5. You can no longer leave Day 5 with the vaccine. In saves where the vaccine was studied on other days, you’ll need to re-enter Day 5.
Soldiers in scenes in the Marrow and the Crucible have stopped misbehaving and now stand where they should.
In the Marrow, we also fixed some potential traps for players who like to explore locations a bit too thoroughly.
Fixed the icon for the White Whip toxin.
Disabled the Eva and Grace dialogue on Day 4 if that day has already ended.
Disabled head-turning for the dead Stamatins in the Cathedral. We delayed this fix for a long time, because, honestly, there was a certain gesture to it—a certain magic.
Fixed two different tutorials triggering in the same Decrees window if you killed Shabnak before opening the Decree Board.
The Decree Board of Hypat the water carrier is now functioning.
