Water Placement Nerf

AI usage disclaimer: This mod was developed with AI-agent assistance. I reviewed the work step by step during development and test releases in my personal Cleanroom modpack with 300+ mods.

This mod prevents players from placing liquid sources mid-air by interacting with vertical surfaces. Attempting to place liquids (like Water or Lava) against a wall without a solid block underneath will be instantly cancelled. The bucket remains filled and no blocks are updated.

Server-Side Only: Because the mod relies strictly on server-side logic and vanilla action-bar messages, it does not need to be installed on the client.

This mod has no effect when on creative mode

Configuration
