Armature parent with automatic weights swaps the legs I'm fairly new to weight painting and armatures, so I heavily rely on automated tools. So far parenting an armature with automatic weights was working perfectly. However this time it's not working.
See screenshot: Right leg is selected, the weight is on the left leg. Same for the lower part. Back bones are not even weighted. 



I'm not sure if this is another setting I overlook or just a bug, but any help is appreciated
I applied the scale and rotation to the model before, so I guess the exact solution was to recalculate the normals. I'm not sure exactly, however applying loc,rot, scale and recalculating normals together fixed the issue.
