Incorrect transparent surface ordering on map habitat

[VReaperV]

Some of the surfaces are drawn in an incorrect order in relation to the window: After the window is rendered: After transparent objects behind the window are rendered: I believe it's an engine bug rather than a map bug since transparent surface should always be rendered back to front.

I agree it's likely an engine bug. I already fixed some of them long time ago but I will not be surprised if some are remaining, or came back.

It may be possible that map bug can produce this though, so we should double-check the map materials.
