The Minecraft Sand and Water bug.

[Jonty800]

I'm not sure if you are aware, but there is a bug in Minecraft Classic, where if you were to place sand above water, the water would disappear.

I was wondering if anyone has any ideas on how this bug could be rectified as a server mod to stop things like this from happening: http://i.imgur.com/97tgC.png

I'm thinking of maybe a check within sand physics where if there is a water block at the drop limit, it will check everytime the sand moves and replace the water if needed, however the bug may stop this from being possible.

I'm also thinking of just leaving it

Thanks

I've run into this problem a few rare occasions throughout my time here. I believe last time I asked there was still no solution. May have changed by now though.

It's only a bizarre client side bug, rejoin the world and the water is all there.

Its not really ideal to get everyone to rejoin

And writing a solution would just decrease performance.

Notch needs to make a classic update!

I remember trying a workaround for this, and I vaguely remember it not working. If you come up with something, please let me know!
