Hi, i recently got back my ma from a server that shut down, and the water i put in goes everywhere. Does anone know what plugin i woud use in singleplayer to get he /replace command and etc? i want to use /replace water 0 to get rid of it! thanks in advance,  TNTBoi23

 

There are no plugins for single player that add that. Single player is intentionally very simple. It's recommended you run a private server locally to get more advanced features.

Disable block physics from the menu and then load the map again.
