SeaBlock 2 Fixed

SeaBlock 2 Fixed is a small, unofficial compatibility and quality-of-life mod for Wanne's SeaBlock 2, designed to fix missing or misplaced recipes and bring back some mechanics from the original SeaBlock 1 experience.

The main goal is to make SeaBlock 2 feel closer to SeaBlock 1 while keeping its improvements and allowing players to customize their experience.

Rather than introducing a complete rebalance, this mod focuses on targeted fixes and optional gameplay adjustments, giving players the freedom to choose how they want to play.

Features & Fixes

1. Mud Landfill — Technology & Recipe Adjustment

Moves the Mud Landfill recipe unlock from Water Washing 2 to Water Washing 1, making it available earlier in the game.
Adds a configurable startup setting to adjust the amount of Mud required to craft 1 Landfill.
Set the value to -1 to preserve SeaBlock 2's original recipe.
Set the value to 5 Mud to restore the original SeaBlock 1 cost.

2. Manganese Oxide — Missing Recipe Fix

Restores the missing Manganese Oxide recipe using Manganese Pellets.
Replaces Natural Gas with Methane, following the original SeaBlock 1 adjustment, since Natural Gas is unavailable in SeaBlock 2.
Ensures the recipe is unlocked through Manganese Smelting 3.
Preserves Angel's Smelting's original recipe quantities and crafting time.

3. Fuel Oil — Configurable Energy Value

Changes the default Fuel Oil energy value from 250 kJ to 1 MJ per fluid unit.
Adds a configurable startup setting, allowing players to adjust its energy value.
Players can restore the original 250 kJ value or choose a different value to suit their preferred balance.

4. Ore Crystallization — Configurable Production Probabilities

Adds independent production probability settings for the six ores produced from Mineral Sludge in Crystallizers:
Saphirite
Stiratite
Rubyte
Bobmonium
Jivolite
Crotinnium
Each ore's production probability can be customized individually from 0% to 100%.
Set a probability to -1 to preserve the original Angel's Refining behavior.
Fully preserves SeaBlock 2's Slurry Multiplier setting, keeping ore production costs independently configurable.

Compatibility

Designed for Factorio 2.1 and Wanne's SeaBlock 2.
Applies targeted modifications to Angel's Refining, Angel's Smelting, and Angel's Petrochem.
Preserves unrelated recipes, technologies, and production chains.
All configurable options are available through the game's Mod Settings → Startup menu.

Philosophy

SeaBlock 1 and SeaBlock 2 offer different gameplay experiences, and not every player prefers the same mechanics.

This mod aims to bridge some of those differences by restoring missing functionality and providing optional adjustments inspired by the original SeaBlock.

The goal is not to force SeaBlock 1's balance onto SeaBlock 2, but to give players more control over their own experience.

Most configurable settings preserve SeaBlock 2's original behavior by default, with the exception of Fuel Oil, which defaults to 1 MJ per fluid unit.

Notes & Future Updates

This is an unofficial community-made fix, not a complete overhaul or rebalance of SeaBlock 2.

Additional fixes and configurable options may be introduced as more missing recipes, progression issues, or differences from SeaBlock 1 are discovered.

Feedback and suggestions are welcome! If you encounter a missing recipe or an unexpected gameplay issue, feel free to report it.
