I am having a very annoying issue when I try to build the control rig for a character. I am met with the following error and google is no help 
Error: RuntimeError: file D:/Epic Games/4.8/Engine/Extras/Maya_AnimationRiggingTools/MayaTools/General/Scripts\Modules\ART_Core.py line 129: Object is already connected.
If I go into “Edit character” I can see the rigs I have named and so on, trying to edit the rig file brings up another error but I can edit the file it creates. This is super frustrating and I have no idea how to fix it :(. Any help quickly is appreciated
