While the Myst Island build is loaded, centering the preview in the middle of the island causes the server to freeze when it attempts to render the preview image ten minutes later. All players time out and I can no longer type into the server console when this happens. Setting the preview center elsewhere prevents any such freeze.
The preview worked, the first few times, but there was a very large number of invisible-painted bricks we used for ambient light sources or quick supports, especially on the giant tree. I went around and began finding each of them and turning off their rendering for a better server preview, and after nearly completing this once, the server froze.
After restarting and redoing the fix, it did not freeze, but the preview was off to the side, and you could only see the clock tower. I centered it, and the server froze ten minutes later.
I realize of course this is not a perfect system, and I should never expect perfect results, but I wanted to make it known, and ask if there's any possible solution to it.
