Artillery Turret AI freezes when mounted upside down under planetary gravity in Multiplayer

【Description】

I have encountered a bug where Artillery Turrets fail to track or fire at targets when mounted upside down on the bottom of a grid specifically under planetary gravity in a multiplayer environment. This issue does not occur in space and seems related to the gravity compensation calculation.


The defence AI correctly displays the target name with a red HUD indicator and the player has a target lock on the enemy. However, the turret barrels remain frozen and do not move to track the target.

If I flip the ship over so the turret is facing up, it immediately begins tracking and firing normally.


Clicking Shoot Once in the control panel temporarily fixes the issue, forcing the turret to synchronize and start tracking again.

Other turrets like Assault Cannons and Gatlings work fine in the same orientation, suggesting this is specific to the Artillery ballistic calculation.


【Environment】

Game Mode: Multiplayer Client side Location: Planetary Gravity Grid: Mounted on the bottom inverted

It appears the AI gravity compensation incorrectly triggers a self-collision check when inverted, or fails to synchronize the vertical aiming vector between the client and the server.

Hello Engineer,

Thank you for reaching out on the forum.

Could you please share a few additional details regarding this issue?

Was the server modded (with active mods) when the issue occurred? If so, could you try making a blueprint of the affected grid and pasting it into a new, fresh vanilla (unmodded) world or server to check whether the issue still persists there?

If the issue also occurs in an unmodded world/server, please share a screen recording/video showing the issue, along with a blueprint of the affected grid or ship.

  • You can access your blueprints files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Blueprints. Select the correct folder where your blueprint is saved (local or cloud), zip the file and attach it here.

You can also upload the blueprint to MOD(dot)IO or the Steam Workshop and share the link with us. When uploading it to the Workshop, please make sure to set the visibility to Private/Hidden so it is not publicly visible to other players.

This will help us investigate the issue more effectively.

Kind regards,

Keen Software House: QA Department
