A deliberate rollback is different from repairing the current build

Owlcat's 1.6 release notice says the previous build remains available through Steam beta branches for players with mod issues or who wish to finish an existing playthrough without the changes. It warns that issues on that branch are unsupported. That makes the branch a compatibility choice—not a general fix for missing DLC or corrupted files.

Branch selection without risking the only save

Owlcat names the legacy build, but players should use the current Steam UI rather than downloading executables from third-party sites.

  1. Exit the game and create a separate backup of the save folder and current mod list/load order.
  2. In Steam Library, open Rogue Trader Properties → Betas/Game Versions and select the branch corresponding to 1.5.0.320 if it is still offered.
  3. Let Steam finish the branch download and verify the displayed build before loading the backup copy.
  4. Continue the old campaign on that branch only; keep saves created there separate from current-build saves.
  5. If the branch is unavailable or the issue concerns DLC entitlement rather than mods, do not force a downgrade—check Owlcat's current support notice.

Community report is not a compatibility guarantee

The linked Steam thread is a player-reported loading/mod symptom. It cannot establish that the 1.5.0.320 branch fixes a different player's issue. Provide exact build, storefront, mod list and a reproducible symptom when asking for help.

Before you play

  • I backed up saves and wrote down the active mods.
  • I verified the actual Steam build before loading.
  • I understand the legacy branch is unsupported by Owlcat.
  • I did not apply Steam-specific steps to another storefront/console.

The June 2026 notice names 1.5.0.320 in Steam beta branches.

Will Owlcat support issues on that legacy build?

The notice says it will not be able to assist with issues related to it.

Does rollback fix DLC ownership errors?

Not necessarily. This branch note is for mods/finishing a playthrough; check current entitlement support separately.

  1. Owlcat Games: Rogue Trader Update 1.6 (Official)

    Owlcat says previous build 1.5.0.320 remains on Steam beta branches for players with mod issues or who want to finish a playthrough without the changes. Owlcat will not support issues on that legacy build. Steam-only branch instructions; other storefronts differ.

    Player discussion prompted by Owlcat's refund announcement. It is not Steam refund advice or a save-repair procedure; eligibility and account decisions belong to Steam/Owlcat's official notices.
