Bug report: GeForce NOW (GFN) Failing to Validate DLC Ownership for Gladius: Relics of War

[Inectha]

Dear Slitherine Support Team,

I am writing to report a serious issue concerning the digital rights management (DRM) and ownership verification of your game, Warhammer 40,000: Gladius - Relics of War, when played through the NVIDIA GeForce NOW (GFN) cloud streaming service (specifically the Performance tier).

Issue Summary: Unauthorized DLC Access
I own only the base game of Gladius: Relics of War on Steam. However, when the game is launched via GFN, the cloud instance is granting me access to content from ALL available DLCs, which I have not purchased.

Expected Behavior:
Only the base game content should be available.

Observed Behavior:
I have access to factions and features from all of the DLC expansions. While the game initially appears to indicate that Demolitions and Onslaught are missing, even the Onslaught expansion visuals are present in the game UI, suggesting that the entire content package is unlocked.

Systemic Problem & Revenue Loss
This appears to be a systemic failure in how GFN's servers handle Steam's DLC verification process for your titles. I have the same 'issue' with other Paradox Interactive games playable via GFN, such as Stellaris and Planetfall, where I am consistently granted full access to content I do not legally own.

As this failure results in players accessing premium content without payment, it represents a significant and ongoing loss of revenue for Slitherine and the development team. I urge you to coordinate with NVIDIA and Steam/Epic (depending on the platform used) to investigate this authentication bypass urgently.

Thank you for your attention to this matter.

Kind regards,
Arjan L.
