That what Dr!fter already mention,
and to more clarify, that specific SM plugin what use this extension, use surely game data file.
Which include game function "offsets" and "signatures".
If those "offsets" and/or "signatures" are not up to date, it lead server crash, error and glitch.

so, list your plugins
rcon sm plugins list

or tell that specific plugin what use DHooks
