The crop function is no longer working.

[simonrp84]

Describe the bug
The crop function of Scene, to extract a smaller area from a large area, does not appear to be working correctly, it is giving an error.

To Reproduce

bbox = (-61.68, 12.33, -59.68, 14.33)

from satpy import Scene
scn = Scene([some_files], reader='abi_l1b')
scn.load(['C01'])
scn2 = scn.crop(ll_bbox = bbox)

Expected behavior
A new scene object containing the cropped area.

Actual results

Environment Info:

• OS: Windows 10
• Satpy Version: 0.26 and 0.27
• PyResample Version: 1.18 and 1.18.1
• Readers and writers dependencies (when relevant): [run from satpy.utils import check_satpy; check_satpy()]

Additional context
Have tested recent versions of satpy and pyresample, and various combinations of the dask, numpy and xarray libraries. Problem the same with all versions I've tried.

False alarm, someone had changed our server settings so both the Meso1 and Meso2 sectors were going into the same directory. Hence satpy was making a stacked area def from the two mesos.
No issue in satpy, so closing this.
