I’ve got several plugins which I imported with piston into my rails  
project. However, when I update them it seems to change them back to an  
earleir revision (e.g. on rspec\_on\_rails it goes from r3320 back to  
r3278 which has lots of changes) – why does it do this? Any clues?

This is really got me, I can’t find anything on this?

Thanks,
