ghostly prim

hey everyone.... Regan here. So a while back i placed a super prim a few meters above the land so that i could rez a sky box and launch it without any problems... after i set up the rentals.. i deleted the super prim that i was using but in this one particular spot on my land it seems to be "stuck" in the air... i am sorry ahead of time if this is the wrong area to post this thread but i didn't know where else to put it. this prim is now a ghost on my land. i hit it when i fly. i can stand on it as if it were still there. it is so annoying. YES i've tried to cntrl alt T to find it. it is not there. anyone have any hints? i've tried mass selecting. selecting only my objects... looking from the ground up. anything i can think of. i'm hoping that someone else has an idea that i haven't thought of yet. please! get this ghost off my land! damn... my poor head hurts from flying into it so often. ouch! I've attached a pic of me miraculously standing in the air on this damn super prim.

You are stuck with ghosts until the next time the sim restarts.

yes, or you can request a sim restart in the support portal or if its in no linden land request it to the sim owner

thanks!
