It's been a while I don't use Poser's hair room, but recently I used it to create wet hair. Looks beautiful, so I moved on to style it using the styling tool on the hair room. Looks even better.

Now, I'm not sure at which point it started to happen (i think it was after I saved the scene and reopened it later), but when I render the scene, the hair is flying all over the screen! On the preview window it's fine, but if I mark "Show Populated" for the hair group, the hair is all over my preview window. Then, if I clear my custom style (by clicking Grow Hair Guides again), it solves the problem, but the custom style is gone. 

In summary, looks like that the custom styled hair is messing up at some point, prolly when I save it. And apparently the same is happening on custom morphs too now. It was working fine before I started messing with custom hair. I tried reproducing the problem by saving and reloading a scene, but it didn't happen. Maybe there's something else playing a part in it. But I'm sure saving it has a big part on the issue.

Well, has anyone else had any problem like this? Not sure if this can be part of the cause but just recently I quit using the 'Use external binary morph targets' setting under General Preferences, so I can use a morph delete Python script.
