.mdl import imports body groups for one model but not another

[BenLubar]

Describe the bug (It's easiest for me to describe this bug as reproduction steps.)

To Reproduce Steps to reproduce the behavior:

1. Download Alien Swarm (appid 630) or Alien Swarm: Reactive Drop (appid 563560).
2. I'm using the contents of AS:RD's pak01_dir.vpk before it gets packed as part of the build process; if you want to replicate this, use a tool like gcfscape to copy the contents of pak01_dir.vpk to the folder it's located in.
3. Import models/aliens/drone/drone.mdl and models/aliens/parasite/parasite.mdl.
4. Drone has 16 body groups, which are all successfully imported.
5. Parasite has 2 body groups, but only one is imported.
6. (That was all using BST, if I try using SourceIO, it fails even though I do have it installed, but if I try to use it directly, it does import the second body group for parasite.mdl.)

Expected behavior parasite.mdl should import both the (yellow, tail) parasite body group (which it does) and the (red, sac) xenomite body group (which it does not currently do).

This seems like an issue with BST. In any case, I would recommend you try the latest beta release since 0.x won't be updated anymore. I checked it quickly and it seems to import correctly with 1.0-beta3.

Will switch to the beta. Thanks!
