Alex's Caves — FAQ

Troubleshooting & FAQ

• Game crashes on startup / "missing Citadel". Alex's Caves requires the Citadel library. Install a Citadel jar that matches your Minecraft version.
• I can't find the cave biomes. They generate underground and can be rare. Dig/branch-mine widely, or create a fresh world so the biomes generate in newly-loaded chunks.
• World-gen looks broken with another biome mod. Large cave/biome mods can conflict. Check the mod's startup warnings and the config to disable overlapping features.
• A mob won't spawn. Confirm its biome exists nearby and that its spawn toggle is enabled in the server config; some creatures (bosses) are summoned rather than naturally spawned.
• Radiation is hurting me. That is the Toxic Caves - craft and wear the hazmat protection before exploring.
