So... how do I convince Steam to do this and leave it alone? ![Confused :?](https://forum.c-rpg.net/Smileys/default/icon_confused.gif)
wont fix it if you updated, but will prevent it in future and for other games (have to do them individually)
Goto Steam 'Library'
right click M&B > properties
Update tab
drop down > do not automatically update this game
