Objects gets deleted when returning... =O.o=

I'm expiriencing that objects that I return on the land i'm working on
(I'm an officer of the Crystal wind group, working at Crystal wind.),
somehow get deleted.

Anyone else expirienced this?

I had two items return to me when trying to see if they finally fixed the auto-return issue going around and they got placed in my Lost and Found as usual.
I also made a new prim and returned it right thereafter without it being deleted.
Are you experiencing this with auto-return or manual returning - And with objects from others or your own?
A little bit more info please cause I am quite curious about this issue.

Usually shows up in eons after , this is update day so expect to be slow, relog usually force inventory to cough and show them in lost & found , not always, sometimes days -.-; pretty rare that one tho.
