Update: I'm wrong :-D
It used to be, eons ago, that when you took multiple selected prims it would go into inventory with a single cube icon like any simple or linked prim (which was tough as there was no differentiation and we'd sometimes mean to rez, say, a chair and accidentally rez a furnished house); when someone returned your objects on purpose or by accident the things went into inventory one by one, which was tough as there was no option to replace the objects in spatial relationship for unlinked builds, and linksets were smaller then.
Then coalesced objects came in. Objects taken as an unlinked group had a "lots of boxes" icon, and if objects were returned they not only had that icon to tell you it was a grouping, but the group retained its spatoial relationships and could easily be re-rezzed and put into position. Unless the grouping contained Linden trees, which could make rezzing difficult (no can do in a sandbox, for example).
It seems nothing causes unalloyed joy; I'd hate to lose coalesced objects but they do cause problems at times. I wonder what changes the new Havok brings to linksets and to coalesced object limits, though. /me sidles over to Aditi to poke around.

This struck a chord with me regarding the Rodeo Incident. If someone had the ability to return objects and did so, either on purpose or inadvertently, then those (3000 or so) prims may have been returned en masse and may have poofed into the Void.
That explains your objects coming up missing, but I had a few (not even close to the limit) for the quest and they were never returned, which needs explaining.
hmm, I allways got multiple coalesced object group thingamings when someone did a return all - and with lummerland and yongnam that was quite recent and definitely above 256 objects in both cases.
