COSTAR
piechart blockentity reflection fix for fabric 1.9-1.12

About this Mod
A simple mod that addresses a questionable design decision in minecraft for versions 1.9-1.12 (fixed in 1.12.1-pre1) that affects fabric: the root.tick.level.entities.blockEntities directive in the piechart uses Class#getSimpleName for the profiler location, leading to fabric having different names from vanilla (and different names in dev than in prod) due to the fact that fabric remaps almost all symbols in the game jar to an intermediary layer. To fix this vanilla parity issue, I just switch out the name with its unmapped equivalent.
See the gallery for an example of what this looks like.

COSTAR server crashes on startup – what to do?

COSTAR officially supports legacy-fabric, ornithe for Minecraft 1.12, 1.11.2, 1.11.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with COSTAR – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if COSTAR consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
