Frequently asked questions

Do I need to do anything after installing Citadel?
No—Citadel works entirely in the background. Once installed, it loads automatically when you start the game and requires no configuration or setup from you.
Why does my game crash when I try to load Alex's Mobs without Citadel?
Alex's Mobs and related mods depend on Citadel's base code to function. Without it, these mods cannot initialize properly and the game will crash during startup.
Can I use Citadel with mods other than Alex's Mobs?
Yes—any mod built on the Citadel library will need it installed. Check each mod's description to see if it lists Citadel as a requirement.
How do I check if Citadel loaded correctly?
Launch the game and check the log file for a message confirming Citadel loaded. If you don't see crash errors mentioning missing Citadel, it's working.
Does Citadel change how vanilla Minecraft plays?
No—Citadel is a library mod that runs silently in the background without modifying vanilla gameplay, blocks, items, or mechanics.
What's the difference between the original Citadel and this Unofficial Port?
The Unofficial Port updates Citadel to work with NeoForge on newer Minecraft versions, while the original was built for older loaders. Both serve the same purpose as a base library.
Will Citadel slow down my game?
No—Citadel is lightweight and designed to have minimal performance impact since it only provides background support for other mods.
Can I remove Citadel after installing it?
Only if you remove all mods that depend on it. If you keep Alex's Mobs or other Citadel-dependent mods, removing Citadel will cause crashes.
Do I need Citadel if I'm only playing vanilla Minecraft?
No—Citadel is only needed if you're using mods that require it. Vanilla Minecraft runs fine without any library mods.
What should I do if a mod says it needs Citadel but I already have it installed?
Verify Citadel actually loaded by checking your game log, and make sure you're using a compatible version for your Minecraft version and loader.
