Hello,
I have found an Alginic Acid soft-lock. I have seen that there was a fix to move the Alginic Acid to Assemblers for SeaBlock, but even without SeaBlock I see no way to craft Alginic Acid.

For example to make the Electrolyser I need Nilaus Paper which needs Alginic Acid, and Alginic Acid is made in the Electrolyser.

Am I missing any alternative recipes here?

You mean you have this mod added? : https://mods.factorio.com/mod/angelsbioprocessing

So you want to make paper to make "Basic circuit board"? Its ingredient "wooden board" can be crafted from paper or from wood.

If its not this mod then can you write list of your mods - or upload and link here your save - so i can reproduce the issue?

Yes. I have Angel Bio Processing and Angel Industries Overhaul.
I have different tiers of circuit boards Grey, Red, Green, Orange, Blue, Yellow, don't know exactly which mod, but I added a new save in the link with my modpack.
Red Circuit Board can be made only from paper. I think this might be the problem, since the Grey Circuit Board can be made from wood.

New Save File with my modpack:

Ok - added second recipe for Alginic acid which can be crafted by hand: https://github.com/Archemide/MomosTweak/pull/13/files
Please check version 1.1.11 : https://mods.factorio.com/mod/MomosTweak/changelog

Btw: 130 mods :) Nice collection ;)

Thanks. :)

It seems that there are still some problems but I don't know if they can be fixed. I tried to disable subsets of mods to see if I can solve the issue, but unfortunately even only base Angel Bob have this problem. Settings might also be an issue.

There are a lot of recipes that are hidden, like:
Basic Circuit Board
Transistor
Circuit Board
Electronic Circuit Board
CPUs

I looked through the recipes and these items appear with an (H) in the Recipe Book and have no recipe, but are used as ingredients in following recipes.

ok, will try to look into it today maybe

Ok. I merged bigger update v1.2.0 - see in changelog https://mods.factorio.com/mod/MomosTweak/changelog and in https://github.com/Archemide/MomosTweak/pull/14

The biggest problem was with "angelsindustries" mod - it heavily changed electronic related things. Now is supported.
Also i added automatic "progression block" test (as described in changelog) - thanks to which detecting similar problems will be faster in the future.

@mlxix please try new version :)

One more thing:
I noticed that mods https://mods.factorio.com/mod/Clowns-Science and "Yuoki" mods are adding alternative recipes for science packs. Those recipes are easy. This kinda conflicts with MomosTweak recipes which are intentionally hard. So if you want harder game then probably is better to not mix those mods with MomosTweak.
