Cache issue?

[Micah Holmes]

I have rebuilt my cabinet code 3 times now. It works for awhile then starts to crash. I have two identical files one works and other crashes:

Working version:

{
  code: "b1cabinet",
  class: "BlockGenericTypedContainer",
  entityclass: "GenericTypedContainer",
  behaviors: [
    { "name": "Lockable" },
    { "name": "Container" },
    { "name": "BoatableGenericTypedContainer" }
  ],
  creativeinventory: { "general": [ "b1cabinet" ],  "decorative": [ "b1cabinet" ] },
  attributes: {
    inventoryClassName: "chest",
    defaultType: "acacia",
    types: [ "acacia" ],
    handbook: {
      groupBy: [ "cabinet" ]
    },
    rotatatableInterval: { "acacia": "22.5degnot45deg" },
    storageType: { "acacia": 189 },

They are not identical, the code is different.

On 12/29/2025 at 5:37 PM, Micah Holmes said:

  code: "cabinet-1",

The code of the crashing version has a `-` in it, which is a big no no as it this symbol is used to separate variants. This means that whenever the game attempts to do any kind of logic for looking up variants it will think that your base code is "cabinet" (because it discards everything after the first variant separator) which generally results in it being unable to find the block or item.

The method that is crashing does exactly that:

`CodeWithVariant` attempts to take your code and replace the "side" variant with the value "east" (if present) but in the process it removes the `-1` and thus becomes unable to find it.
