I've removed the CubeCraft config because they've announced they're moving to a new anti-cheat similar to Grim, so it's likely the old config is/will be outdated, so I've removed it from the list until a new config is made.
The old config can be found by pulling it from before the delete commit: https://raw.githubusercontent.com/CCBlueX/LiquidCloud/d9512f6b82daea45f15ecb31939bf9f5c9262f94/LiquidBounce/settings/nextgen/cubecraft.json
Let me know your feedback on the old config, it may still work, in which case I can/will bring it back.
