TaCZ Tweaks 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 (1.21.1). You can switch loaders with one click in the panel.

TaCZ Tweaks officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.1, 1.20. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with TaCZ Tweaks – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if TaCZ Tweaks consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
