VoxelMind Companion 0.8.18

• Fixed Builder edits switching worlds when the owner entered another dimension while a design was being generated or its building steps were still running. Updated backends send the observed target dimension with the coordinates; all steps and the undo snapshot stay in that world.
• World, player and fairy facts retain full dimension identifiers, including custom namespaces. A fairy left in another dimension can be addressed there.
• An invalid or unavailable target dimension returns an execution error.
• If Minecraft unloads the target chunks, the command's native error and actual partial block count are reported; the edit never moves to the owner's new dimension. This update does not keep chunks force-loaded.
• Undo and changed-block receipts now refer to those same executed edits after a dimension change.

Reproduced with the released 0.8.17 mod in a real Minecraft client. The native regression probe checks delayed edits and delivery after a dimension change in both directions between Overworld and Nether, verifies that the other dimension stays untouched, checks execution receipts, and performs undo from the other dimension. It also checks unloaded-target partial failures and refusal of invalid and unavailable dimensions.
