A fire has reportedly torn through the Prague offices of STALKER 2: Heart of Chornobyl developer GSC Game World overnight. The report comes from Vortex (translated via Google), which cites two anonymous sources and claims to have a photo of the damage, which it is not able to publish. It says that the fire “devastated” the equipment and interior.
According to the report, GSC Game World occupies three floors of the building. While only one has been affected, that floor hosts the back-up servers for the studio’s data. The blaze has been blamed on an electrical fault, and required the evacuation of between 20 and 30 people. The damage bill is estimated at 1.5 million koruna (approximately $65,750).
This was echoed by another GSC Game World employee with the handle Mol1t on the official Stalker Discord channel. Mol1t's full message is as follows:

"It is true. Fortunately, none of the employees or office staff were injured in the accident.
A fire broke out in our office in Prague on Thursday. Even though the fire was successfully put out, one of the office floors now requires a full restoration. Further details of the accident are still being investigated.
We express our deepest appreciation for your questions and the words of support we have been receiving.
No anomaly, not even a "Burner", will make us stop in our pursuit of our final goal. We've dealt with worse than that before. This is fine."
