Unfortunately the way GitHub triggers workflows doesn't allow them to run on a schedule on a non-default branch. So this branch (updater_workflow) has to be the default. Switch to a different branch to see the source code of the mod (for ex. master -> the master branch of the mod)
To recover lost commits, use the commit hashes from GitHub's reflog (add ?per_page=#&page=# to the log URL to increase the page size (maximum is 100, default is 30) and/or specify the page number (default is 1)).
