That command would have resulted in:
1. File or folder `/home/nginx/crap/mymods`
2. All directories at `/` _(in theory)_
3. All files and directories in `/home/nginx/crap/`
moved into last directory given by `*` in `/home/nginx/crap/`. As in:
ls -d /home/nginx/crap/*
afile1 afile2 dir1 dir2
Then everything would be put into `dir2`.
If the last entry of `*` was a file the command would have failed as you cannot move files and folders into a file.
As the last file in your `gist` post is `tree.txt` you most likely did not move any files – and something else has happened.
See if you have the `env` command available.
