T5SP dedicated server (r5316) not appearing in server browser - only r5164 servers visible""T5SP dedicated server (r5316) not appearing in server browser - only r5164 servers visible

[MattPursuit]

Dedicated T5SP (Black Ops 1 Zombies) servers running revision r5316 do not appear in the Plutonium in-game server browser, despite being fully operational and visible in the Plutonium API at https://plutonium.pw/api/servers.
Steps to Reproduce:

Set up a dedicated T5SP server using the latest Plutonium updater
Server updates to r5316 automatically
Server appears in the API with correct hostname, map, gametype, and player data
Open the in-game server browser in Plutonium T5 Co-Op
Search for the server by name - no results
Scroll through entire server list - server not visible

Expected Behavior:
Server should appear in the in-game server browser like all other T5SP servers.
Actual Behavior:
Server does not appear in the browser. All T5SP servers currently visible in the browser are running r5164. Servers running r5316 are present in the API but invisible in the browser.
Evidence:

Server confirmed running: sv_running returns 1
Server confirmed in API: ip 23.147.40.37, port 31209, game t5sp, hostname [TLS] Official Kino 24/7
Heartbeats successful and continuous
All other visible T5SP servers in the browser show revision 5164, not 5316

Possible Cause:
The in-game server browser appears to be filtering out T5SP servers running r5316. This may be a revision mismatch filter or a client-side filtering issue introduced with r5316.
Workaround:
Players can connect directly via console but this is not ideal for a hosting business.

There are visible servers which are running the latest version. It’s a network issue on your end.
