I rezzed the package box and went to package my building, but the box disappeared. Where did it go?
Sometimes, SL doesn’t display small objects that are far away. This is so that your computer doesn’t have to spend time drawing things that probably don’t matter very much. The object isn’t actually gone, but you can’t see it. The distance calculation is done based on where your avatar is, so even if you zoom your camera over to where the package box should be, it won’t be displayed. The solution is simple: just walk over close to where you rezzed the package box, and it will appear. If the box still doesn’t appear, try relogging. Sometimes SL just really gets confused and needs a kick. If even THAT doesn’t work, then send me a support request. I’ll send you a copy of a tool I have that will tell you teh exact position of any package boxes within range.
