TMT - Cobblemon Brush Fix
If you have been exploring the Cobblemon mod for Minecraft, you know how immersive it is to dig up fossils and uncover ancient Pokémon with a brush. But a frustrating bug in Cobblemon 1.7.3 can crash your game right when you are about to make a big discovery. The TMT - Cobblemon Brush Fix is a simple, server-side datapack that steps in to prevent those crashes, letting you and your players enjoy a stable world without losing progress.
What Is the TMT - Cobblemon Brush Fix?
This datapack is a targeted solution created by Totalniy and the Totalnaya Mod Team (TMT). It addresses a specific conflict in Cobblemon 1.7.3 where using a brush on certain blocks triggers a client crash. The root cause lies in how the mod handles brush interactions, and until an official patch arrives, this fix temporarily disables those problematic interactions. The result is a crash-free experience that keeps your server online and your fossil hunts intact. Because it is purely data-driven, the fix adds zero performance overhead and does not alter any other Cobblemon mechanics.
Key Features of the Datapack
- Crash Prevention: Disables the broken brush interactions that cause client crashes, ensuring uninterrupted gameplay.
- Server-Side Only: Players do not need to download or install anything on their own clients. Just drop it into your world folder.
- Lightweight Design: The fix uses only data pack functions, so it has no impact on server tick rate or memory usage.
- Seamless Integration: Works silently in the background. Once loaded, you can forget it is there while you hunt for fossils.
- Easy Removal: When Cobblemon releases an official patch, simply delete the datapack to restore full brush functionality.

- Download the TMT - Cobblemon Brush Fix .zip file from your trusted source.
- Locate your Minecraft world folder. For a single-player world, this is inside the
savesdirectory. For a server, it is the world folder you specified inserver.properties. - Open the
datapacksfolder inside that world folder. If it does not exist, create it. - Place the downloaded .zip file into the
datapacksfolder. Do not unzip it. - If the server is running, use the
/reloadcommand (requires operator permissions) or restart the server. The datapack will activate automatically.
Once installed, you can verify it is working by typing /datapack list enabled in the console or chat. You should see TMT - Cobblemon Brush Fix in the list. No additional configuration is needed.
Compatibility and Requirements
This datapack is built exclusively for Minecraft 1.21.1 and Cobblemon 1.7.3. It works on any server platform that supports datapacks, including vanilla, Fabric, and Forge. Since it is server-side, players joining your world do not need to install anything extra. If you are using a modded launcher, the process remains the same—just drop the file into the world’s datapacks folder. For those who prefer a streamlined experience, the foxygame.net launcher offers a one-click install option for the TMT - Cobblemon Brush Fix, automatically placing the datapack in the correct directory and keeping it updated alongside your other mods.
How the Fix Works Under the Hood
The datapack overrides the vanilla brush interaction with a custom function that simply does nothing when a player attempts to use a brush on a block. This prevents the game from calling the problematic Cobblemon code that leads to crashes. Because it is a data pack, it does not modify any mod files or require Forge/Fabric hooks. It loads after the Cobblemon mod and takes priority over the broken interaction. The fix is passive—it only activates when a brush is used, so your server’s performance remains untouched during normal gameplay.
When to Remove the Fix
The TMT - Cobblemon Brush Fix is intended as a temporary measure. Once the Cobblemon development team releases an official update that resolves the brush crash, you should remove this datapack to restore the full brushing mechanic. To do so, simply delete the .zip file from your datapacks folder and reload the server. You can also disable it via the /datapack disable command if you want to keep the file for later. Keep an eye on Cobblemon’s changelog for news of a permanent fix.
Why This Fix Matters for Server Owners
Running a public Cobblemon server means managing player expectations and uptime. A reproducible crash can drive players away and create a flood of support tickets. By adding the TMT - Cobblemon Brush Fix to your server, you eliminate a known pain point instantly. It is a zero-configuration, drop-in solution that shows your community you are proactive about stability. Plus, because it is server-side, you do not need to convince every player to update their client mods—just install it on the server and the problem is solved for everyone.
