No Stone Left Behind [NSLB]
No Stone Left Behind is a NeoForge utility that swaps mined ores for stone-type blocks, and it is meant for server owners who want that behavior.
What it does
When a player mines a block whose registry name contains an ore keyword, the mod replaces that block with a matching stone block such as cobblestone, cobbled deepslate or netherrack. It reads the register name of each block and looks for keywords, so no separate list of blocks is needed. If no keyword matches, nothing is placed. The replacement happens after a one-tick delay following the break, and the block placed afterward is the stone variant.
The mod runs on the server only, so players join without installing anything. It is published for NeoForge 1.21.1, with a beta build bt1 dated 2026-09-02, and is released under All rights reserved, so it is not open source. The author describes it as a simple, small mod still in beta testing, and warns server owners about this.
Key features
Keyword-based replacement
Mined blocks are matched by keywords in their register names, and the matching stone block is placed in their position.
Creative mode conversion
Blocks are converted in creative mode as well, so the replacement can be checked without survival play.
One-tick replacement delay
The new block is placed one tick after the original block is mined, which keeps the change separate from the break.

What the author says
Ever wondered where stone went when you mined ores? Now, when mining an ore (not to be confused with a block of raw {ore name}), it will replace it with cobblestone, netherrack, or cobbled deepslate.
