System Information
Operating system: Windows-10-10.0.17763-SP0 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00

Blender Version
Broken: version: 2.83 (sub 8), branch: master, commit date: 2020-03-14 00:31, hash: acab745078
Worked: Never

Short description of error
UDIM switch from Tiled to Single and back to Tiled will make another tile pink.
We can not reload the image, the only way that I know to fix this is by delete or remove the image data (or do Purge All) and re-open the image or manually adding UDIM Tiles on Image editor.
The expected behaviour should be whenever changed to Tiled it will reload all the other UDIM tiles. The same issue also happened in 2.82a.

Exact steps for others to reproduce the error

Open this attach blend file.
Change from Tiled to Single Image and switchback to Tiled.

This is a UI/UX issue. source is actually a property of the image itself. Changing this modifies the image and as mentioned in this ticket the image needs to be reconstructed by the user.

IIRC this property was added during b2.80 to be able to open a new image and configure some basics via the node (source/colorspace). the source is a destructive option and IMO should be removed from the image texture node or should be made non-destructive.

I would propose to remove the source option from the texture nodes.

This issue is now, mostly, fixed with the checkin noted above. If you switch from Tiled to Single and back to Tiled, just use the Refresh button in the image editor to reload back to a good state now. Keeping the 'source' input around is actually necessary in cases where Blender fails to "guess" the UDIM format correctly. The user needs the ability to go in and fix things up inside the Image editor, so keeping 'source' available there is still necessary at least.

If this is acceptable, we can mark this task as Resolved now.
