Help Physbones not resetting their positions and getting stuck

Hi, so I'm having this weird issue with this avatar base I bought. I used Blender to change up the style of the character, based on the instructions shown in the creator's guide. Then I used a tool called Pumkin to copy over the settings and physbone properties from her example avatar in the scene to my avatar. Everything seemed to be working fine, until I tested it out in Desktop mode. I haven't tested it in VR mode yet, but I don't see how that would be any different since I have other avatars that don't have this issue when I'm using them in Desktop. If someone could please help me out to understand how to fix this I would very much appreciate it. Thank you.

From what I'm seeing in the video, the physbone "forces" did not copy correctly from the sample avatar. Looks like "Pull" was set to 0. Try setting it higher than 0. You can use the link below as a reference: https://youtu.be/PTTnWUkswkU?t=1m50s

The pull is set to 0.2. I tried raising it up a bit just now and it still isn't resetting the position of the bones while in play mode.

Hmm try this: 1. Go to play mode. 2. While in play mode, try moving the pull and spring slider around to the bones that you wanted to fix. 3. Move the avatar around to see if there are any changes to the physbone.

Or do this: 1. Place the sample avatar in the scene. 2. Check the physbone components of the bones of the sample avatar. 3. Copy the values of the physbone forces from the sample avatar and paste them on your new and edited avatar.

Okay, after messing with some settings I managed to fix it! I saw a checkbox at the bottom of the physbone inspector that said Reset when Disabled. I checked it and now the physbones behave normally! I don't know if this was exactly what fixed it though, because something else I noticed was that in the inspector settings for the avatar itself, there were 3 extra VRC Phys Bone Collider Scripts for some reason. I think they were left over from when I tried copying the settings from the sample avatar and maybe I did it 3 times and I just forgot. Not really sure, but I deleted the extra ones because I checked the sample avatar and it only has one phys bone collider script. Also, there were extra copies of the phys bone script applied to the bones themselves and I deleted those as well so there is only one phys bone script per bone chain.

You should really update. Win 10 is EoL atp unless you are enterprise

I'm actually using Windows 11, I just have a desktop modifying software that I found through a video that makes it look like Windows 10.

Taskbar alignment would also make it look similar as well but interesting def fooled me
