Cargo depot unloading animation plays for unit module with no workers

Describe the issue
No gameplay effect, just an annoyance. I have a small cargo depot with a unit module that has no workers but is otherwise active. The unloading animation plays continuously, but no products are actually unloaded.

To Reproduce
See attached zipped save file.

Expected behavior
Don't play the unloading animation when there are no workers in the unit module.

Additional context

• Game version: 0.3.11f Beta

I believe this was fixed before we launched EA.
