i know that the changelog said the scripts for this were fixed since 1.2.5b but i still haven't been able to get it working.
this is on Crucial 2 version 1.3 with:

create-mc1.16.5_v0.3.2d
CreateTweaker-1.0.0.18
ContentTweaker-1.16-1.0.0.develop.19
as the only additional mods added in manually, is there something i'm missing here?

@tyreforhyred I'm experiencing the same exact issue. Curse Forge seems to prefer Create v0.3.2c for some reason, but since the script is the same I'm getting the same error. I got it to work eventually by replacing every instance of fluid:create:milk with fluid:minecraft:milk (note the "minecraft" instead of the "create", since the fluid seems to be registered differently than expected by the script).

@Beetrootmonkey ahh this makes a lot more sense, i remember reading that Create switched over to forge's fluid handling system for milk in the latest versions, thanks so much for the help!

This is a fresh install with Create 0.3.1c

I've been told CreateTweaker also needs to be installed. Next version will warn you about it if it's not included.

Can confirm, no more errors now, thanks 👍

Keeping it open as a caution until it's fixed.
