Thanks for the response.
I take it that by "new navigation, customer service or advice." you are referring to one or more of the forums here.
The other forums here are in Chinese. I don't speak Chinese. I'm using this forum to ask questions in English in order get answers in English because that is what this forum, the OverSeas zone forum, is for.
I can't efficiently use a machine translation service such as Google Translate because it doesn't work on these forums.
Since I don't speak Chinese, I can't tell which of the hundreds or thousands of posts I might need to Google-translate a passage at a time.
So, I repeat the question, in hopes of getting an answer in English so that every English speaker who comes to this forum can find it in English in this forum. Every time an answer is posted in English in this forum, it becomes available to everyone via search engines.
Sorry if I seem a little annoyed but this forum used to be translatable by Google or other computer translation services and now it's not at all, apparently, on any translation service I know of.
What is the solution to the problem of prim objects not appearing at all though terrain, avatars, sky, etc. do appear?
