Missing Half-Life 2 entities

A known bug in Create a Mod configures Valve Hammer Editor to load base.fgd instead of halflife2.fgd. This issue will be resolved in a future SDK update.

To workaround this problem:

1. In Valve Hammer Editor, choose Options under the Tools menu.
2. Select your mod's configuration in the Configuration combo box.
3. Click the Remove button next to the Game Data Files list. This will remove the unwanted base.fgd file.
4. Click the Add button next to the Game Data Files list and choose halflife2.fgd.
