When finishing a task that is assigned to some "Goal", chain link is not added for that goal.
Maybe adding also a "full support" - show chains for goals in application - would be also great. I mean that chains on this page: http://www.toodledo.com/organize/goals.php (for Pro accounts)
But fixing that bug with not adding chain links would be enough.
This issue appears to be on Toodledo’s side. The interface Toodledo provides to apps such as ours does not provide a way to directly update the goal chain. If you are not seeing a new link in the chain after completing a task within UTL, then Toodledo’s server did not update its internal records after the synchronization.
Currently, the only workaround we are aware of is to make sure to mark the task as complete from Toodledo’s web site.
Regarding support for viewing a goal chain within UTL, feel free to submit this in the “New Feature Suggestions” area.
