No note, no contact from any of the 200 or so employees at the school who could have moved it.

There are two possibilities I can see: one, I forgot to mix up the combination after I locked it up today, and anyone could have just unzipped the lock; two, someone was able to crack my lock and move the bike without leaving any apparent damage to the lock. I will change the combination now and be more careful in the future, but does anyone know of a way to crack an Otto Lock without leaving apparent damage?
