This mod is inspired by the many videos I saw about this kind of mod, but didn't link the mod in their description - so I made it myself.
Features
Everything you place in one chunk gets copied to all other chunks. Everything you break gets broken in all other chunks. Enjoy the chaos.
Warning: Especially on lower-end systems, keep your simulation distance low. It runs okay with higher values, but especially if you have an older CPU, placing / breaking a block freezes the game for a few hundred milliseconds when the simulation distance if above 16 (or so) chunks.
This mod is server-side only, meaning it only does anything when using it in Singleplayer worlds or when it is installed on the dedicated server. Your server's players do not need to have it installed on their clients.
Issues
Please report any bugs or other issues you encounter using this mod on the linked Github issue page.
Modpack Usage
If you for whatever reason want to, you may use this mod in modpacks and on servers without first asking me for permission, or even crediting me, as long as you do not pretend that you made this mod and do not ask for payment in exchange for access to your modpack. Credit is appreciated, tho :3
