Project being changed to Undefined on Completed Tasks
I've encountered an issue after I complete a task and then archive the project. Basically, the project listed on the task changes to undefined when you archive a task.
This is a problem when viewing the Completed History because of several projects that have similar tasks. Because of archive the projects, I can't tell which task goes with which project (let me know if you need me to e-mail you a screen shot).
Thank you very much for your report, I've been able to reproduce this issue and I've passed it to the developers. We'll fix this issue soon.
I think this is related - visualization of completed tasks doesn't show any undefined i.e. archived projects which is a shame.
