Bug ID: 51266
           Summary: S.T.A.L.K.E.R. Anomaly 1.5.1: AI Targeting Is Broken
           Product: Wine
           Version: 6.10
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Version of application:
1.5.1 from
https://www.moddb.com/mods/stalker-anomaly/downloads/stalker-anomaly-151

Wine versions tested:
Wine-staging 6.9
Wine-staging 6.10 from 3 sources: Fedora repos, WineHQ repos, TkG

Synopsis:
Starting in Wine 6.10, most of the AI in S.T.A.L.K.E.R. Anomaly are incapable
of targeting other NPCs or the player and NPCs are unable to fire their weapons
at a target. The player is still able to perform normal functions. Game's
console (~) doesn't show anything unusual when compared between 6.9 and 6.10.
Of the three sources of 6.10 tested: one from the Fedora repos, one from the
WineHQ Fedora repos, and a Wine with additional patches, all three exhibited
the same behavior.

Video of issue in 6.10:

Zombified NPCs don't target and fire at the player, only move to the last
position of the player if they make noise or injure them. Zombies don't melee
the player, simply continually walk into the player. NPCs aren't shooting the
zombifieds or zombies. Enemy NPCs run away and don't fire at the player. The
only functioning AI is the bloodsucker which is still partially broken and
takes several seconds to acknowledge the player is there. The issue is
intermittent, sometimes a single AI will begin working after several seconds.
However after relaunching the game the behavior will change and they may stop
working.

S.T.A.L.K.E.R. Anomaly is free and standalone so can be tested easily. Only
requires d3dx11_43, d3dcompiler_43, and d3dx9 to run, with dxvk to get
acceptable framerates. Debug mode can be entered by launching the game with
-dbg and hitting numpad 0 to enter flycam, enter to teleport player to camera
position. There's an unrelated Wine issue with the game crashing when opening
the options menu, so set resolution with the launcher if needed.

I haven't tested if this issue also happens in the base S.T.A.L.K.E.R. games or
other mods. And yes, I don't have any mods to Anomaly installed.

As for debug logs, I have no idea where to start.
