... between the post below and the problem I experienced?
I have a sky garden at a height of about 750 metres. One morning I went up there, and saw there were oblong plywood blocks rezzing on either side of the garden. They were appearing, tumbling through the air, and then coming to rest in one of several places. In the sky there were 'clumps' of blocks at different orientations, in a line about 100m long. I couldn't see what was actually rezzing the blocks.
I went over to the blocks, and discovered they had no name and no maker's name. I tried returning them, and although they could be selected and the pie chart appeared, when I clicked 'Return' or 'Delete' nothing happened.
So I called live help, and Data Linden appeared. When I took him up to the sky garden, he was unable to see the blocks, although I could see them. We both took photographs; mine show the blocks and his do not.
When I went up to the sky garden next I was unable to see the blocks - I don't know whether they had been removed or whether they were still there and I couldn't see them. I would like to know what they were, however. I didn't hear any more from Data, and so I wonder whether anybody else has an idea.
