Bug #543

FM - Old session overwrites progress when game is opened on multiple tabs or devices

Status:	In Progress
Priority:	High
Added by:	percemer_coolgames on January 9, '26
Assigned to:	Unassigned
Due date:
Reported for:	Patch Notes Version 1.72.0-7 Auto
Platform:	All platforms

Steps to Reproduce

1. Launch the game on Device/Tab A and make progress (e.g., earn currencies, level up, etc.).
2. Keep the game idle until being disconnected from the server.
3. Without closing Device/Tab A, open the game on Device/Tab B or another browser tab.
4. Return to Device/Tab A.

Explanation

Actual result: The older session state overwrites newer data, causing loss of items and progress.

Expected result: When a newer session exists, any older session should be fully invalidated and unable to be relaunched. The game should always preserve the most recent session state and prevent older sessions from overwriting current progress.

Note: this issue can occur everywhere but that’s very frequent on Reddit.
