RPG Prefab Houses

1.6.6 for Minecraft 1.21.1 (NeoForge)

Now on Minecraft 1.21.1 with NeoForge

• RPG Prefab Houses now runs on Minecraft 1.21.1 with NeoForge, as well as on 1.20.1 with Forge. It's the same mod: the same 20 styles, the same Customise settings and the same Builder's Hammer, and a design code builds the same house on both.
• The Forge 1.20.1 version stays available and gets the same updates. This is an extra version, not a replacement.
• Needs NeoForge 21.1.1 or newer (tested on 21.1.259). Install it on the server and on every client.
• Houses you placed in a 1.20.1 world are still recognised when the world is opened in 1.21.1, so you can still extend them with the Builder's Hammer. Back up your world before moving it to a new Minecraft version.
• Decorated pots and bells now turn with the house, like every other block (in 1.20.1 they kept their facing).
• Tested with Sodium and Iris shaders.

Land claims respected

• With some claim mods (such as Open Parties and Claims) a house could be placed inside another player's claim. Placing a house, or extending one with the Builder's Hammer, now also asks the claim mod whether you may build there, and is refused if any claimed chunk under the house or its mine says no. Claims from mods that already worked (such as FTB Chunks) and spawn protection are respected as before.

Undo gives the grass back

• Grass, mycelium and nylium under a house turn to dirt while it stands. Undo now puts them back as they were.

Adventure mode

• Adventure-mode players follow Minecraft's adventure rules: placing or extending a house needs a Prefab Catalogue or Builder's Hammer in hand whose "Can place on" list names the ground there. Before, adventure players could place houses anywhere.

The land-claim, Undo and adventure changes are also in Forge 1.20.1 version 1.6.6.
