How to fix In Search of Past Glory quest bug in Stalker 2? Why don’t Dvupalov take blueprints in S.T.A.L.K.E.R. 2

S.T.A.L.K.E.R. 2 continues the series’ tradition of immersive but occasionally bug-ridden experiences that can halt your progress unexpectedly. While developers have addressed numerous issues through recent updates, certain persistent bugs remain problematic for players navigating the Zone. One particularly frustrating obstruction occurs during the critical main storyline mission In Search of Past Glory, specifically when attempting to deliver crucial items to Professor Dvupalov.

After successfully locating the reclusive scientist, you’ll receive instructions to venture into the treacherous X5 Laboratory complex to retrieve the essential Suppressor Blueprint. Upon returning to Dvupalov’s bunker with the required schematic, multiple failure scenarios can prevent story advancement. The entrance to his underground facility might become permanently sealed, or the dialogue tree necessary for blueprint handoff fails to activate properly. This leaves players stuck with an important quest item they cannot deliver, effectively blocking progression through the primary narrative arc.

The most reliable non-mod solution involves temporarily abandoning your attempts to interact with Professor Dvupalov for an extended period. The exact trigger conditions for this bug remain undocumented, but community testing reveals that reloading earlier save files typically proves ineffective. Implement a strategic time-wasting approach: utilize bedrolls in distant regions for multiple sleep cycles, complete several side missions or faction tasks, then return to the scientist’s location. This organic reset method has demonstrated consistent success rates among the player community when other alternatives fail.

For optimal results, dedicate approximately 2-3 hours of gameplay to other activities before returning to Dvupalov. Engage with trader quests, explore uncharted anomalies, or hunt for artifacts—these activities seem to reset the quest flags that control blueprint acceptance. Many players report success after completing 3-4 side objectives or sleeping through 2 full day-night cycles at minimum.

If the waiting strategy proves impractical or the bug persists despite your efforts, consider employing a modification that forcibly advances the main storyline. Download the UEtools utility package here. This lightweight modification activates the developer console interface without compromising game stability or save file integrity. After installation, access the command interface using the tilde key and input this specific sequence:

• XStartQuestNodeBySID E08_MQ04_Teleport_OnStart

Executing this command will immediately initiate the subsequent primary mission, Once More unto the Breach, bypassing the blocked Dvupalov interaction entirely. This approach guarantees progression but may skip minor narrative elements, so consider creating a backup save before implementation.

Important precaution: Always verify mod compatibility with your current game version and create manual saves before installing any third-party modifications. While UEtools is widely regarded as stable, unexpected conflicts can occur with certain gameplay modifications or older save files.

Proactive save management represents your strongest defense against progression-blocking bugs in the Zone. Maintain multiple manual saves before initiating critical story missions, particularly before entering laboratory complexes or interacting with key NPCs. Community forums suggest creating dedicated save points before traveling to X5 and again before returning to Dvupalov. This strategy ensures you never lose significant progress to unexpected glitches.

Additional community-discovered workarounds include completing the “Doctor’s Quest” side mission chain before approaching Dvupalov, as this seems to stabilize certain quest flags. Monitor official patch notes for fixes addressing this specific interaction—developer attention to persistent bugs often increases following community reporting spikes.
