Xstreet magic box problem

I keep 3 magic boxes on my land and to hide them I put clear texture on them.10 days ago I went to add some new stuff and hit Ctrl Alt T and they were missing.all other alpha textures showed red.I keep spares so i rezzed 3 new ones,tested delivery, all was OK,
A moment ago I went to my boxes to add an item and they would not show,This time I did a test delivery and the stuff got delivered,WTF.I logged off and changed my viewer to the RC.Hit show alpha and low and behold I had 6 boxes the others were there all the time.
Whats going on? Anybody had this problem?

I've had prims appear to be missing, and later they turned out to have been there all along. More often than not, switching which group tag I am wearing seems to make them become visible again to my client, though I haven't a clue why that works.

This may totally not be your issue, Blot, but last week sometime I received a notice that a new version of the XStreet Box (something like 3.1) was now available and was much more stable than the former version. Since having multiple boxes on various sims I had not been experiencing any difficulty, but I transferred to the new boxes anyway.

But if your boxes are disappearing to begin with...not sure the new version would help. Could give it a try though. (Assuming you haven't of course. )

Yes, in 1.22 I had some clear prims that wouldn't show with highlight transparent, almost as if they were invisiprims. Drag-select in edit mode did highlight them. The problem went away in 1.23.
