Hello, When I do git clone -j10 --depth=1 --branch=develop --no-tags --single-branch --recurse-submodules --shallow-submodules --remote-submodules https://github.com/boostorg/boost.git . Or git clone --depth=1 --shallow-submodules --branch=develop https://github.com/boostorg/boost.git . git submodule update --init --remote --checkout --recommend-shallow --recursive --single-branch --jobs 10 --depth 1 I get the error: fatal: Unable to find current origin/develop revision in submodule path 'libs/callable_traits' In the trace I see that git clone is called without the `--branch=develop` even though `git branch` reports `develop` and `.gitmodules` sets 'branch = .' on every submodule. trace: built-in: git submodule--helper clone --require-init --path libs/callable_traits --name callable_traits --url https://github.com/boostorg/callable_traits.git --depth=1 --single-branch trace: built-in: git clone --no-checkout --depth 1 --separate-git-dir /home/nick/boost-repo/.git/modules/callable_traits --single-branch -- https://github.com/boostorg/callable_traits.git /home/nick/boost-repo/libs/callable_traits I tried different versions: git version 2.34.1 git version 2.39.2.windows.1 git version 2.40.0.windows.1
