You did run a  "diff /tmp/tmp.YI0xO6M46g/bugged/file 
/tmp/tmp.YI0xO6M46g/patched/file" (ignoring what ever options you provided)

The patch file (file.patch) will have the instruction of making the 
/tmp/tmp.YI0xO6M46g/patched/file based on your 
/tmp/tmp.YI0xO6M46g/bugged/file, so when you run the patch command it 
will notice that the changes already has been applied to 
/tmp/tmp.YI0xO6M46g/patched/file and asking if you want to remove the 
changes so that you get a /tmp/tmp.YI0xO6M46g/patched/file that is 
looking like  /tmp/tmp.YI0xO6M46g/bugged/file.

I guess you want to patch the /tmp/tmp.YI0xO6M46g/bugged/file then it's 
simplest to go into /tmp/tmp.YI0xO6M46g/bugged and use the -p option to 
make the patch command to ignore the directories.

Another alternative could be "cp -a /tmp/tmp.YI0xO6M46g/patched/file 
/tmp/tmp.YI0xO6M46g/bugged/file"
