I had the same thing happen immediately after the last server roll out. I was working on my latest HUD. I dropped it on the ground in Sandbox Goguen to edit it and could not 'take' it back into inventory. I didn't want to leave this commercially sensitive item rezzed inworld for all to see and copy. I relogged, cleared cache and still could not take it. I made the whole thing transparent and was able to remove all the scripts from it but still it would not allow me to take it. Sandbox Goguen has a 2 hour auto delete yet it was still there some 5 hours later! Finally, I decided to "wear" it (which I would never recommend wearing anything direct off the ground having lost stuff that way in the past) and viola! I was wearing the transparent, unscripted HUD in its usual attachemnt point on my screen. From there, 'detaching" it was easy. Let me know if you can 'wear' the tank and if this helps. Chur, Rez.
