This is fixable - I have done it myself. It's not possible to add an outgoing transition on an active (or draft of an existing active) workflow. So you work around this by:
* Create a copy of your workflow
* Add the outgoing transitions that you want to add
* Change the workflow scheme to point at the new workflow
It's not super elegant but if you need to work around it you can.
