Repository size reported incorrectly
I had a problem with a very large repository (fantasticmachine/odette2014) with it being 1.6GB. I have since cleaned up the repository using the instructions you provide and now a git count-object --v shows the size pack as being 198838. However the soft limit warning is still being displayed and the size in the Repository Info screen is still shown as 1.6GB.
I've taken the liberty of tagging Brodie Rao on this as I see a similar issue was dealt with a couple of months ago.
