TuffBlocks 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 4 GB RAM is allocated and the loader matches the mod version (1.20.6). You can switch loaders with one click in the panel.
Is TuffBlocks compatible with fabric and forge and quilt?
TuffBlocks officially supports fabric, forge, quilt for Minecraft 1.20.6, 1.20.5, 1.20.4. 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 TuffBlocks – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if TuffBlocks 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.
