Autumnity - Spawn Compat
by Kanadeyoru
Autumnity - Spawn Compat is a Forge compatibility patch that integrates the Autumnity and Spawn mods so both work together in one pack.
What it does
The patch adds spawn entries for Autumnity's snail family to the Spawn mod: Snail, Escargot, Potted Sweet Berries, Mucus, Snail Eggs, and the Snail Shell variants. Shell tile slabs and stairs are included, along with Autumnity Snail Goo and Spawn Mucus Block.
The project aims at smoother coexistence in modpacks by removing duplicate mobs, items and blocks. Where a duplicate is removed, dependent content is redirected to the remaining equivalent item, so recipes and other references keep working. The changes list names each removed duplicate. Autumnity Snail Goo block crafting recipes are adjusted, and Spawn Mucus Block is crafted using Autumnity Snail Goo.
Autumnity - Spawn Compat requires Autumnity and Spawn. It is published for Forge only, for 1.20.1, and runs on client and server, so the server and every player need it. The license is All rights reserved, and the code is not open source.
Key features
Snail spawn entries
Snail, Escargot, Snail Eggs and the Snail Shell variants are added to Spawn so they appear in the Spawn catalog.
Duplicate removal
Duplicate mobs, items and blocks that overlap between the two mods are removed, and dependent references are redirected to the remaining item.
Snail goo and mucus blocks
Autumnity Snail Goo and Spawn Mucus Block are included, with the Mucus Block crafted from Snail Goo.
Shell tile variants
Snail Shell Tiles come with a slab and stairs, so builders get matching shapes from the same material.

What the author says
The goal of this mod is to make mods work better together in modpacks by removing duplicate items, mobs, and blocks. It ensures that anything dependent on the removed items still works by redirecting those dependencies to the remaining equivalent item. ## List of changes ### Removed Duplicate Mobs - Spawn Snail ###…
