I've fixed this but my web host is having trouble with FTP right now. You can get the fixed code from Github[github.com].

I just pushed the fix to the repo, let me know if it works for you.

Nope, this is the repo[github.com]. You don't need my permission to branch, but you may want to ask if I'd take a feature before spending too much time on it!

It's a bug in the exporter. I've got a fix already and will wrap it up with a few other changes I have half-completed this weekend, hopefully.

You can also uncheck the bone's Deform property, which will prevent them from being exported in the first place.

You should ask on the Crowbar forum. This is unlikely to be a problem with the importer.

Are you importing decompiled animations? It sounds like the animation might be a delta, i.e. something in which the position data is added to the base pose rather than replacing it.

It's a UI redraw error completely unrelated to exporting. That explains why the normal error popup didn't appear. Seems that the active exportable index is getting out of sync with the list. I'll look into it soon.

I didn't think you'd be able to screw that up but you did! I'm impressed. Please take a screenshot of the full error which appears in a large black box. If you can't then please use Window > Toggle System Console and take a screenshot of that with the entire error message in view.

If it happens again take a screenshot.
