Steps to reproduce:
Create task
Create subtask
Create section in subtasks (tab + N)
Create another subtask
Expand subtasks from project list view
Select first and last subtask using [shift] + [click]
Drag subtasks to parent task level
Asana crashes when it tries to lift the subtask section to the parent task level.

PS: I indicated moderate, but it might be more urgent as I learned that all subtasks after the subtask section end up orphaned with neither project nor parent task.
I’m now finding the tasks again through search.
I think the sections are floating in the void.
Flagging @Forum-team to determine if this belongs in English Forum > Critical Bugs
Definitely not great behavior, but not sure how critical it is - most people don’t even know about subtasks sections; I could be wrong but suspect they are a very little-used feature.

Wow, I had no idea task sections were a thing.

It looks like this:

The trick to adding a Subsection is to:
Open the Task Detail pane for the task in which you want to add the Subsection,
Click to focus your mouse cursor somewhere (any field) within the Task Detail pane (otherwise you’ll get a Section in the Tasks List instead of a Subsection here).
Use …

I rest my case, your honor.

You can even create them with a “create subtasks” rule action, and the will convert into project sections when you convert the task to a project.
Ok, probably not critical. But I’d make a point of fixing it anyway, with tasks potentially ending up in the void.
