Hi! We have just landed on Arig, and are trying to progress. We believe we are in a softlock situation, but might be missing a step or something.

We are pumping sand and sifting it, getting iron ore, copper ore, coal, stone, pure sand and steam. we can create calcite from pure sand and water from steam, but we want to craft raw diamond for the trigger tech of the science pack. doing this however requires silicone, which it looks like we can make with a recipe using Calcite and Pure Sand, but that recipe is made in a Press. Building the Press requires glass, which looks like it requires Silicone.

Are we meant to trigger the 50 raw diamond tech before heading to Arig?

We ended up setting up raw diamond crafting on Nauvis to trigger the tech and unlock the Heavy Arig Sand to Bobmonium recipe so we can craft Silicon that way. A new roadblock appeared where we need a Chemical Furnace to craft Glass from Silicon, but that requires Clay Bricks, which seem incredibly daunting/impossible to craft at Arig. Clay and Sand are easy enough, but Lime is a bit unclear for us. We need Limestone, which seemingly only comes from washing viscous mud water, but the seafloor pump does not work on Arig. Lime could also be gathered as a byproduct from Sulfur Dioxide synthesis from Calcium Sulfate, but that requires Fluorite which also is a dead end.

How is Arig supposed to start? We are close, but it feels like we have gotten softlocked twice in quick succession now...

You can make them on Nauvis, from crystal slurry.

Yeah, before it was done by pump, probably recipe for limestone is missing:(

For clay bricks you can try to downgrade (make savegame backup) to version 1.1.37 (or version 1.2.12 if your are playing with factorio 2.1) and use a seafloor pump on Arig. This way, you can at least make progress until it is patched. Be aware, all 1.1.38 and 1.1.39 recipe will be removed after downgrade (e.g. Arig sand washing clay, vulcanus specific rocket fuel and fulgora specific lead ore)
