Frequently Asked Questions

Help I have the item stacking glitch

• There is a glitch where if you hold an item then suddenly new items of that same type will no longer be able to stack on that item
• "if i tried picking up 4 blocks of wood one would just go into another corner while the other 3 were in a stack"
• FIX: update to version 1.6.443 or higher

Where did the the custom swords go?

• The new swords (like ice and frost) are now in KnY Extra Additions
• curseforge.com/minecraft/mc-mods/kny-extra-additions
• https://modrinth.com/mod/kny-extra-additions
• https://github.com/YeeticusFinch/KnY-Extra-Additions/

My world creation is stuck at 100%

• This means that Mt Fujikasana isn't importing properly
• Try upgrading to the latest version of Kimetsunoyaiba Tweaks
• Otherwise, you can fix it manually:
• Go to your .minecraft folder --> kimetsunoyaibamultiplayer --> mt_fujikasane_cache
• If this folder is empty, then you've got a problem
• https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/tree/main/region
• ^^ Download all the region files from this GitHub link
• Place all those .mca files into minecraft/kimetsunoyaibamultiplayer/mt_fujikasane_cache/
• Reload the mod and try again

Where can I get help with this mod?

• I don't usually check comments on the mod page
• If you need support, please join on discord: https://discord.gg/W8K962vQFT
• Or send an email to carlfromca@gmail.com

The game crashes on mod loading

• Make sure you have forge 47.4.0
• Make sure you have the forge versions for 1.20.1 for all the following dependency mods
  • Kimetsunoyaiba
  • Mob Player Animator
  • Player Animator
  • GeckoLib
• Make sure you don't have Optifine, it's completely incompatible

My spawns are messed up, there are no Hashira or Kizuki demons or named characters spawning?

• Go into the config for Kimetsunoyaiba Tweaks (aka Kimetsunoyaiba Multiplayer)
• Disable enhanced spawning
• Enhanced Spawning will prevent named characters, hashira, and kizuki demons from spawning - outside of raids and quests and special biomes/structures

How do I configure this mod?

• I recommend using a config mod, like Configured or Forge Config Menus
• Alternatively, you can go into your minecraft folder --> config --> Kimetsunoyaiba Multiplayer
• You can edit the .toml files directly

Missing textures

• Yes sorry I haven't finished making all the assets yet
