Perhaps the Dynamic Bone Collider is the cause.Hey guys anyone knows how to make the hair not so buggy? View attachment 2908075
Do the following before switching the character in the scene
Select Dynamic Bone Collider → Open KKPE's Adv. mode → Remember what items are checked.
After switching the character, you will probably find that unnecessary parts (Bone such as Acc Hair and Clothing) are checked, so uncheck all of them and restore them.
I think this will work.
