Protect My Redstone
by Izulo
Protect My Redstone warns a singleplayer player before leaving a world while redstone machines are still running, so farms and flying machines are not stopped by accident.
What it does
Before the player chooses Leave World, the mod checks for active redstone in the loaded chunks, including chunks kept loaded by chunk loaders. When it finds any, a warning screen lists the chunk coordinates with the most activity, so the player can see where the machines are. The detection threshold is configurable, which lets small circuits be ignored.
A countdown timer before the Leave World button gives the player time to cancel, and it can be adjusted in the configuration.
The mod runs on client and server, and it is built for Fabric 1.21.11 only. It requires Cloth Config API and Fabric API, and Mod Menu is an optional addition for opening the settings. Protect My Redstone is released under the MIT License and is not open source.
Key features
Active chunk detection
The mod scans loaded chunks for redstone ticking, including chunks held loaded by chunk loaders far from the player.
Chunk coordinate list
The warning screen names the chunks with the most active redstone, so the player knows which area to check.
Adjustable countdown
A timer before the Leave World button can be set in the configuration, giving a window to cancel the exit.
Per-component toggles
Each redstone component type can be included or excluded from the check, and the detection threshold filters out small circuits.

Protect My Redstone warns you before logging out of a singleplayer world while your farms are still running. Instead of accidentally breaking a farm or stopping your flying machines by closing the game, you'll get a warning screen showing which chunks have active redstone, allowing you to turn them off.
