I found this bug in the editor: If a bone of the current entity is selected when loading a new entity from the animation, the game often crashes.
I also found an oddity: when you use the same graphics for an entity and for skinning naija, the entity is 2x bigger. I don't know if it is intended, but it can be quite confusing, especially when you need to add new parts to naija, and so need to create her as a separate entity.
