I have seen this before, but I ignored it, now it is an issue I cannot fix.

Water in editor is in its place, but a part of water mesh is not drawn in game and is cut along the area line/end, I have noticed this just now, it appeared suddenly and without known reason.

I tried to widen the water; change the terrain, but it is there and I can’t fix it.
I made new water, and the issue is still there. I tried to delete the area files and rebuild, nothing helps...

You can see it on the pictures below, how it looks in the editor and in game. Just right click and open pic in new window...

Hello,

I see that you're referring to 1.0 which is unfortunately discontinued.
The only supported version right now is 2.0 which is available since 16 months already.
If you're experiencing a similar issue with 2.0 then please attach a sample project, and I'll investigate the issue.
