>>> x264 7d0ff22e8c96de126be9d3de4952edd6d1b75a8c Downloading Fetching all references Could not fetch special ref '7d0ff22e8c96de126be9d3de4952edd6d1b75a8c'; assuming it is not special. warning: refname '7d0ff22e8c96de126be9d3de4952edd6d1b75a8c' is ambiguous. Git normally never creates a ref that ends with 40 hex characters because it will be ignored when you just specify 40-hex. These refs may be created by mistake. For example, git checkout -b $br $(git rev-parse ...) where "$br" is somehow empty and a 40-hex ref is created. Please examine these refs and maybe delete them.
