Overview:

This mod adds compatibility beween Alex's Caves, Create and a few Create addons. Also includes some minor, non-intrusive compatibility additions for a few unrelated mods.

Other affected mods:

Features:

General:

• adds many new recipes, most of which fall into 3 categories: compatibility (such as Alex's Caves ore crushing recipes), QoL (using Create recipes to more easily obtain certain Alex's Caves resources), and utility (using Create recipes to make certain Alex's Caves blocks/items renewable)
• adds an optional resource pack with compatibility textures (like making Create's chocolate look like Alex's Caves chocolate)
• adds a new recipe type that makes use of both mods' mechanics
• fixes certain bugs when these mods are used together

Cave-specific: 

Magnetic Caves

• makes several Create blocks and items affected by magnets.

Primordial Caves

•  renames Create's Limestone to Dolomite since Alex's Caves also has Limestone (if the optional resource pack is loaded).

Toxic Caves

• adds Bulk Corroding recipe type, which works by placing Acid in front of an Encased Fan. Currently used to rust/oxidize all blocks that interact with Acid. 

Abyssal Chasm

• retextures and renames Alex's Caves' diving gear and the Copper Valve to make them more distinct from Create's (if the optional resource pack is loaded). 

Candy Cavity

• retextures Create chocolate to match Alex's Caves color palette (if the optional resource pack is loaded)
• makes Create sweets appear in Candy Cavity chests, and Gingerbread Men will try to steal them
