Deleting a column in board layout - do the tasks get deleted?

Hi @Adam_Raoof :wave: thank you for reaching out!

Apologies for the trouble here. What you are saying is correct. When you delete a Section, all tasks nested in this Section - Completed and incomplete tasks, will be also deleted. You can learn more about it in the following guide article: https://asana.com/guide/help/projects/sections#gl-delete-section

I would recommend you to have a look at this post: How to delete section in project without deleting completed tasks? - #5 by Arthur_Davis. You might find this workaround useful for the future.

Additionally, to recover the deleted tasks you can follow the steps outlined here: https://asana.com/guide/help/tasks/actions#gl-undelete-task

Lastly, I’m listing below a few threads we have in the #productfeedback category regarding this topic. Feel free to cast your vote on any of them.

I hope this helps Adam! Please let me know if there is anything else I can help you with!
