There appears to be an issue with the Darkness Trigger system used in underground locations.
When a player enters an underground bunker with an active Darkness Trigger, the darkness effect works correctly.
However, if the server crashes or restarts while the player is inside the Darkness Trigger area, the darkness effect is no longer applied when the player reconnects.
The underground area becomes fully illuminated, even though the player is still inside the configured Darkness Trigger zone.
