Commented Issue: Localized satellite package not copied to main package [3543]

Configuration:
Private nuget server version 2.6.0.1
Nuget package manager version 2.6.40627.9000

Main package conf:
- id : MyDll
- version : 1.0.0
- language : en-US
- content:
lib/net45/MyDll.dll
lib/net45/MyDll.Resources.dll

Satellite package conf:
- id : MyDll.fr
- version : 1.0.0
- language : fr
- dependency : id="MyDll" version="[1.0.0]"
- content:
lib/net45/fr/MyDll.Resources.resources.dll

When I install the satellite package with the package manager, accessing my private nuget server by http, 'PdfTemplates.1.0.0.fr\lib\net45\fr\MyDll.Resources.resources.dll' is not copied to main package 'PdfTemplates.1.0.0'
Comments: I tried installing my packages on another project, same result. I tried installing my nuget server on a local IIS, same result. I tried installing a localized package from the official nuget server, it works. So I guess the problem is really from my nuget server, but it's a default one, no modifications, I'm just using the Nuget.Server package. I even tried creating a new server from scratch and testing with another computer, it still doesn't work. Any idea what I can do to find the problem?
