I'm almost crying because such a stupid thing happened – I imported an animation from an MB file into Blitzkrieg 2, using the plugins described in this tutorial, and Heroes just messed it up... The model ended up on the character's back, which happens sometimes... It's so stupid that I don't know what to say... The interface in the Blitzkrieg map editor is similar to Heroes, so it's easy to figure out. You just need to specify the root bone and the number of frames in the animation, and that's it.
