Probably an already known issue but just wanted to be sure
If I try to download one of the windows nightlies (krypton 32-bits or leia 32-bits and 64-bits) , I always ended on an 404 error
In the same time, downloading the latest stable release works
If you try to download kodi 64-bits nightly for windows, you are sent to http://mirrors.kodi.tv/nightlies/win64/master/ but it seems the good link is http://mirrors.kodi.tv/nightlies/windows/win64/master/
