I try to keep support up for the latest drop of Minecraft. Updates to newer Minecraft
versions may be delayed from time to time, as I do not always have the time to immediately update my mods.
Unsupported versions are still available to download, but they won't receive new features or bugfixes.
NeoForge ports are available for Minecraft 26.1 onwards.
Usage
The Fabric API is not required on Fabric. This mod is not required on clients.

Modify Player Data server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2). You can switch loaders with one click in the panel.

Server lagging with Modify Player Data – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Modify Player Data consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
