When part has collision group that collides with nothing, touch events will still fire on that part.
Replication:
Make a new CollisionGroup, uncheck all boxes with other groups.
Assign this group to part.
Subscribe to Touched event of that part.
Result:
Event fires when part touches any other part.
Expected behavior
CollisionGroups should not trigger touched events with groups that do not collide with assigned CollisionGroup on part.
