Grand Workshop Core — Minecraft 1.20.3 — compatibility fixes
Curse Maven Snippet
What's new
Minecraft 1.20.3 Fabric compatibility correction.
- Fixes recipe-book unlocks that Minecraft 1.20.3 rejected because their item predicates used a newer data format.
- Corrects native registration of the workshop seat and Porter. Seats still support mounting without being saved as permanent entities; Porters retain their saved data.
- Preserves existing blocks, item identifiers, furniture geometry and textures.
The exact Complete package passed 54,568 server assertions and client checks for 14,536 block-state models, the Porter, furniture displays, catalog selection and preview-item protection. Core with the five published expansions passed 36,795 server assertions. These are regression checks, not exhaustive feature coverage.
Requires Minecraft 1.20.3, Fabric Loader 0.19.5 or newer, Fabric API 0.91.1+1.20.3, and Java 17 or newer. Shipped bytecode targets Java 17; isolated runtime verification used Java 21.
Core is the modular base. Add the workshop expansions you want; do not also install Complete.
