As ssen in the video (https://vimeo.com/52218780), the second monster have some parts not well positioned. This is because the anchor points are not well read from the SCML file.

To solve this we must change the line 552 of SpriterNode.cpp to check if the pivot_x and pivot_y exists as a property in the object. If the property is not set, i takes 0 as the default number, but Spriter uses 1 as the default value. The code should look like this.

CCString pivot_x = object->getPropertyCCString("pivot_x");
CCString pivot_y = object->getPropertyCCString("pivot_y");
timelineKey->setAnchorPoint(
ccp(pivot_x->compare("")==0 ? 1 : pivot_x->doubleValue(),
pivot_y->compare("")==0 ? 1 : pivot_y->doubleValue()));

I don't have Cocos2d-X set up in XCode, so i can't test it. Feel free to try and fix this. Thanks.
