When weather containers are thrown into environmental accumulators, then the effect which renders the rising weather container, renders it way too transparent. I have only been able to reproduce this on windows computers, so I think it's a windows only bug?

In 1.7 we also have this problem, except that maybe its not rendered at all? (or just rendered VERY transparent, so we can't see it). Again I have only been able to reproduce this on windows.
