Another Game Q and A

This is the latest Q and A from Scott Evans:
21 - STRAY OBJECT SCOPE
The scope of objects that could become stray includes loose, valueless objects (such as the black pillars) as well as loose valuable objects and strategic objects. However, if a Dual-Locked object gets separated from the mat, that's considered "Field Damage" and the referee will restore it (Rule 27).

The Inventioneers: This means that as soon as any strategic object ("strategic objects are defined as team-supplied objects which you or your robot may use as tools or aids"), scoring objects (the loops, for example) and/or non scoring objects (pillars) are not in their original position they can be removed by the referee and that if the bridge, for example, comes off the mat it will be restored to its original position!
