Fix water delete straight lines of all materials at the high of the water surface. they are only 1*1 pxel in size but extrem long

Some better English and explanation would help. I have no clue what you're talking about. Screenshots maybe?

So do I... Long 1x1x? parallel lines of missing blocks, at "sea level", spaced a chunk apart...

I think I know what s/he refers to.

Sry, it was late...

They are only 1 Pixel deep in ground and filled completly with water. All spaces they reached are filled with water too.

You see the lines in sand and infront of the blue building. I can make more screens with alot more of these lines when you want.

I actually had same problem on world, but i didnt know worldedit is causing them o_O

have you tried fix lava?

no i dont want destroy my world again

I am not sure whether this is a WorldEdit issue or an issue with Bukkit. I've only seen this problem occur with Bukkit (not hMod or Single Player Commands), so I am led to believe that is so.

Current they only appear when i use fixwater.

I had heard of it happening after a big worldedit mistake and subsequent undo which "crashed". I don't know which operation the mistake involved, but it may have been fixwater.
The fact that it seems to always appear at "sea level" would make sense if it's connected to fixwater. And the way the lines are spaced a chunk apart, and have differing start/end points and lengths could also be related to some water somewhere too.
