Current query:
UPDATE sessions SET session_resource = <current resource> AND session_online = 0 WHERE <time condition>
Should be:
UPDATE sessions SET session_online = 0 WHERE session_resource = <current resource> AND <time condition>
Should be fixed in Pluton code too, Azhàr/Zed are ok, they still use the old code.
