Transport bug deleting attached friendly units

[Amundr]

Sorry if this is the wrong forum - I couldn't find one dedicated to bugs reports.

Today I experienced a bug that ended up deleting my ally's units. I was standing with 16 of my own units and had 13 ally units attached - for a total of 29 units. In the same tile (Negroponte in Greece) I had 16 transport ships at port. I clicked on my stack and pressed the "Attach to transport" button, and then clicked on the ships and sailed out to sea. My units went along with the ships, but the ally's units that were attached to my units disappeared.

There is a dedicated sub forum

This is probably the same bug as in this bugreport. Maybe you can post in that report and mention that it also affects allies. If you have a save in which allies are attached to your units(and get deleted when doing what you describe), it would be good if you attach it to the bugreport.
