@ACHMartin the issue is when you do newds['z'] = stacked.z. In the last versions of Xarray multi-index levels have each their own (real) coordinates, for consistency and clarity we soon won't support assigning a multi-index to a single coordinate of a Dataset / DataArray like that.

I think that in other places we still do support it with a deprecation notice, but apparently in your example this is not the case. unstack doesn't work because the multi-index(es) and the coordinates of newds are not consistent.

I don't know exactly what is your real problem, but from now on you should avoid implicitly assign a multi-index with xr_obj["my_coord"] = ... or xr_obj.assign(my_coord=...). Instead you should re-create the multi-index, e.g., in your minimal example newds = newds.set_index(z=["across", "along"]).

Hi @DWesl,

Your example is working with the main branch, it has been fixed in #6889.

```python

after #6889

arr2.unstack("index0")

<xarray.DataArray (index2: 2, level_0: 3, level_1: 5)>

array([[[ 0, 1, 2, 3, 4],

[ 5, 6, 7, 8, 9],

[10, 11, 12, 13, 14]],

[[ 0, 1, 2, 3, 4],

[ 5, 6, 7, 8, 9],

[10, 11, 12, 13, 14]]])

Coordinates:

* level_0 (level_0) int64 0 1 2

* level_1 (level_1) int64 0 1 2 3 4

Dimensions without coordinates: index2

```
