Could someone explain me why my custom water loads chunks? At the updatetick method it checks if the vanilla water is next to it and replaces it with itself. Curretnly it loads every chunk while doing this and replaces everything.

 

You can see what i mean on my Dynmap. I never went to the dark blue area.

Hmm, is there any way to prevent the loading of the chunks, so the water doesnt spread any further?

Hmm, it simply says false the whole time, even though standing at the position.

I tried it with the coordinates of the block and then with the coordinates of the block that is in the range to replace.

ugh, your right. Totally forgot that. It seem to spread again. I gonna reply again if it works on the server.
