Nothing. You died and lost your stuff. Just like in singleplayer.

 

Pick yourself up, get back to work, and be more careful next time!
Enjoy your time on the server. :D

 

if any items that still in water can be recovered - same as singleplayer

 

Falling into water should negate damage?

 

@RaginDevonian probably drowning

 

She just stated she fell in

 

Perhaps you fell onto a block you thought was a water block but while falling you moved one block too far and died? That happened to me before, maybe it happened to you?

 

Not to sure on this one, but if you fall into water thats 1 block deep, dont you still take damage?

This could be why you died.
