System Information

  • Kernel version: 6.17.0-20-generic

  • GE Proton [10-34:]

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

  • Network features (in‑game chat and PvP) are unavailable after changing compatibility tool / reinstalling Steam & the game.
  • Characters and inventory load locally, but network name and PvP rank are missing.
    Attempting to send a chat message shows popup: "you are not the owner of this character".
  • Two data strings observed in main menu: KcGAN1lqK6d38i9h3TcQ9WFoK0d2 and 160c4b7b-519f-4977-81ac-ba0459fefb09.

Reproduction

Launch Vampire's Fall 2 via Steam on Ubuntu using Proton (AppID 4264230).
Log in with your Steam account. Characters and inventory load normally.
Attempt to use chat or join PvP.
Observe the popup: "you are not the owner of this character"; network name and PvP rank are missing.
(Optional) Revert compatibility tool to the previous working Proton — network features restore (confirming issue is tied to compatibility tool change).

Notes to include in the issue:

Exact Proton build tested was GE Proton 10-34, and the previous working tools - Proton hotfix, Proton experimental/
State OS Ubuntu 22.04
I attached a compressed archive with shortened logs (vf2-collected.tar.gz) and that you i provide the full logs on request.
