Hey there community,
We have tracked down an issue with the Mm puppet that we are working to resolve, but might cause some slight issues for you in the meantime. Don't worry! It shouldn't cause you any real problems but there are a couple of things you can do just to make sure you don't get any nasty side effects.
If you do encounter this issue you will notice it when editing or remixing a character. The update tool will show that there is a pending update on the puppet itself, if you hit update with the "Replace local changes" button ticked in the bottom left corner of the screen, you may see your character change to something you don't want. The simple solution is:
On a character with this unexpected update to the puppet, before hitting the "Update Now" button ensure the "Replace local changes" button is UNTICKED.
This should mean that you are able to carry on working with no unwanted changes made to your character.
If this still causes some problems for you please do let us know here on the forum and we will do our best to help you out!
