When running a workflow that is started by another workflow and has a task action, the action sends out multiple emails for the same task, however only one of the emails actually links to the task, the other emails all open with: 'Sorry, something went wrong'.
- Identify the child workflow where the multiple task emails are coming from.
- Add a one minute pause at the start of this workflow.
This behavior is due to a bug that was resolved in build 184.108.40.206 or Nintex Workflow 2013. Upgrading to build 220.127.116.11 or higher should also resolve this issue.
