Description

Obsidian Conflict dedicated server crashes on tier0.dll when SM is loaded.
OC version i'm using: https://www.moddb.com/mods/obsidian-conflict/downloads/oc-135-unofficial-mountfix-full-installer

Accelerator dump: https://crash.limetech.org/myy4o2s5qjlv

Downgrading SM to 1.10.0.6545 fixes the crash.
Downgrading MMS is not needed.

Steps to Reproduce

1. Install Source 2007 Dedicated Server.
2. Install Obsidian Conflict.
3. Install latest dev MMS and SM.
4. Start the server.
5. Wait for the initial map to load.
6. Change the map either via sm_map or changelevel.
7. Server should crash.
