TFMG Vat Processing Fix

A focused bugfix addon for Create: The Factory Must Grow (TFMG). Install it alongside the original mod when your setup encounters the issue described below.

The problem

A chemical vat can incorrectly accept or reject a recipe, stop on usable output space, or fail to place every result of a completed batch.

Why it happens

The original processing path makes separate, incomplete checks of ingredients, machine attachments and output space. Some checks depend on map order or assume a fixed output capacity.

Scope of the fix

• Checks a complete recipe batch using copies of the actual items, fluid tanks and capacities before committing it.
• Rechecks attachments and resources while processing, consumes the required ingredients once, and places the complete set of results.

Recipe definitions, processing durations, heat requirements, fuel efficiency and tank capacities keep their original values. No Steam & Steel progression or balance changes are included.

Compatibility

• Minecraft 1.21.1
• NeoForge 21.1.235 for Minecraft 1.21.1
• Create 6.0.10
• TFMG 1.2.0, installed separately

This release targets the original TFMG 1.2.0 implementation. Later versions and Community Edition are not claimed compatible. Install the addon with the required mods; for multiplayer, use matching versions on server and clients.

From Steam & Steel

The fix was developed while maintaining Steam & Steel SMP, our custom Minecraft 1.21.1 NeoForge server modpack using Create and TFMG. This addon is independent of that modpack and does not require SteamSteelCore.

Beta / Feedback

This is a beta release. These fixes grew out of problems encountered and tested by players on our Steam & Steel SMP server, within its specific modpack. Compatibility with other modpacks still needs feedback.

If you encounter a crash, an error or unexpected behaviour, please leave a comment with your Minecraft, NeoForge, Create, TFMG and addon versions, plus steps to reproduce the problem. We will investigate reported bugs and work on fixes.

The standalone addon has local regression and Mixin-application checks. The server experience described above is the origin of the fix, rather than a claim that every standalone configuration has been tested.
