Hello Talandar99 !
In the research phase before moving on to the Chemistry Science Pack, the "Titanium Plate" recipe in the "Titanium Processing" recipe requires "Titanium Dust."
So, I can't craft titanium plates.
I use a lot of mods, so I'm not sure if this is the exact cause of the issue, but I found this mod in a related mod on Factorypedia and am posting here.
If this is the problem with this mod, please fix it. Otherwise, what should I do? I really want to play with this mod without disabling it.
I'm using a machine translation, so please understand if it's not smooth.
Thank you.

As far as I know neither ASP or vanilla chemical science recipe require require titanium plates.

I have no idea which mod causes that, because it does not happen to in vanilla game with pelagos installed.
I need to know mod that cause this to hapen in order to replicate it and see what I can do

Thanks for the reply :)
Since I don't know what the problem is, I looked for any titanium-related recipes that seem to involve ingredients or techniques.
https://mods.factorio.com/mod/bztitanium
https://mods.factorio.com/mod/scrap-industry
https://mods.factorio.com/mod/crushing-industry
https://mods.factorio.com/mod/alloy-smelting

The four mods above seem to be related.
Of them, the bztitanium mod above seems to be the cause of the error.
Of course, I don't know anything about modding or coding, so I'm not sure.
I'm a beginner, so I haven't been to Pelagos yet, but judging by its information page, it looks like a planet I'd really like to visit! Please help if you can.
Thank you!

Thx for list.
Pelagos generally was not tangled a lot in vanilla code and mechanics so it and related mods can be removed and added back relatively painlessly if you have not been there yet if that's roadblock for you.
I ll see what I can do and let you know.

I want to go quickly and see the coconut X)

took me a while but should be fixed in 0.18.1
let me know if it works fine now
