Hello everyone, I'm trying to edit the weights of my clothes that I've skinned on to my character and when I apply a 1 to my verts for the Pelvis for example, the mesh gets deformed weirdly. 
My suspicion is that it happens because I'm using a custom t-pose to create the clothing in Zbrush and to Apply them on to the model but I didn't have this problem in previous models I've done before CC v4.2.
Because it used to work fine, I assume this is a bug with the latest version but it really messes with my workflow so If anyone has a workaround or if the Devs can look into it, I'd appreciate it!
Below is an example of what the scabbard looks like before and after I apply weights.
