Incorrect decompilation of the physics model for props from Half-Life 2 beta.

[ghost]

For some unknow reason Crowbar does not correctly decompile physics model for props from Half-Life 2 Beta.
For example, when decompiling the props_c17\barrel01a.mdl model, smd file for the physical model is created, but it contains only a static bone in the center, and there is no physics mesh itself.
However, if decompile the Alyx model, then the physics mesh is present in the smd file of the physics model.
