Bug #1399

Unnecessary Editor Plugins Included in Steam Build

Status:	Open
Priority:	Medium
Added by:	Anonymous on October 7, '26
Assigned to:	Unassigned
Due date:
Reported for:	v.0.25021757 Auto

Steps to Reproduce

1. Search for the cause of a graphical settings issue
2. Noticed that the public build includes and mounts editor plugins
3. These plugins are visible in Manifest_UFSFiles_Win64.txt and the generated Engine.ini at launch
4. Observe the following plugins:
5. - Plugins/ClaudeBridgeLegacy52/ (.uplugin + Config/FilterPlugin.ini)
6. - Engine/Plugins/Developer/Concert/ (ConcertMain, ConcertSyncClient, ConcertSyncCore)
7. - PythonScriptPlugin, UVEditor, GeometryMode, BlueprintHeaderView, ConsoleVariablesEditor, Bridge (Quixel)
8. Check the network for any active connections (no ports are listening, only HTTPS leaderboard and UDP for multiplayer)
9. Determine that this seems to be an oversight in packaging rather than a vulnerability
10. Suggest excluding these plugins from the shipping target to lighten the build and remove unnecessary code for players
11. Prefer to report the bug through the bug report system rather than Discord for this type of discovery
