In my current configuration (with only 1 package), I somehow managed to break the ✨ Reverting any changes in the checkouts directory ... step. The following problem occurs: An error occurred: Command '/bin/bash -c "git -C '/[MyProjectPath]/.accio/checkouts/PMJSON' reset HEAD --hard --quiet 2> /dev/null"' returned with error code 128.

When I copy this repo to another folder and run the failing command (git -C '[NewPath]/PMJSON' reset HEAD --hard) manually, there's still an error: fatal: Could not parse object 'HEAD'.

Maybe this problem is related to the fact that after initializing accio and then switching to a branch where it wasn't installed yet, I performed a Reset All of the original repo via Sourcetree to reset the .accio folder. Maybe this had an effect on the recursive subrepos (those within .accio/checkouts), so that after switching to the accio branch again, running accio install failed. Still weird, that the checkouts folder survived the git reset... 🤔
