Will this work with other mods that add new biomes ?
In almost all cases yes! As long as you choose the Islands world type registered biomes added by other mods will spawn as islands. As with everything however there are exception where mods implement their biomes differently or lock them to their own world types and we can't do anything about that.

Islands server crashes on startup – what to do?
Most common cause: wrong forge 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 (1.17.1). You can switch loaders with one click in the panel.
Is Islands compatible with forge?
Islands officially supports forge for Minecraft 1.17.1, 1.16.5, 1.15.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Islands – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Islands 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.
