Valve Broke Legacy CS:GO Community Server Plugins

During yesterday’s scheduled Steam maintenance (3/17/26), plugins that rely on SteamIDs to save user data seemingly broke out of nowhere. This includes plugins like SourceBans++, ranking plugins, loadout plugins, anti-cheat plugins, etc.

Basically anything that relies on SteamID handling is currently broken.

On affected servers:

* SteamIDs appear normal in console (e.g. via status) * But plugins fail to recognize or persist player data * In some cases, SteamIDs resolve to STEAM\_ID\_STOP\_IGNORING\_RETVALS * Data does not save between reconnects/map change * Admin permissions are not applied

This issue started yesterday and is still ongoing. It’s also happening across multiple servers, not just a single setup.

At this point it doesn’t seem like something that can be fixed server-side. Posting to see if others are experiencing the same issue and to bring attention to it.
