Here's what the script editor prints out. - Built a biped proxy. - Generated a single joint hierarchy skeleton with the rig, with a prefix - Selected control on rig and pressed Delete Rig - Result is rig stays and is not removed.

I'm not getting any errors in the script editor. To repro, 1. Build default biped proxy. 2. Create Single Hierarchy joint chain 3. Try to delete rig 4. Rig won't delete

Hi Dustin, Thanks, I'll send you the maya file in a bit. If it makes a difference I did use a preface when building the Rig.

I just checked and the lookdevkit plugin is loaded.
