[English is a second language for me]

EDIT : Problem solved, thanks to @kingarthur for the explanation !

Hi ! First, thanks a lot for your whole pY modset. It's truely amazing and I can't wait to try pY : Alien Life !

I crafted thousand of splitters before but for some reason, I can't anymore because rubber is needed for the recipe. I notice before that rubber was included in the ''total raw'', but it was working even if I didn't had any.

I don't know if it's a bug, but rubber appears on the ''total raw'' section when handcrafting them, but it is not when looking with ''What is it really used for?''.

Thanks a lot !

theres a recipe to make transport belts with rubber that gives more than the standard recipe. you have no belts in your pockets so it looks like the game is trying to use that second recipe to craft the belts to make the splitters.

it shows in the total raw because its one of the raw inputs based on that buts its not in the splitter recipe itself so its not going to show up in fnei or what is it really used for.

Thank you very much ! I'm new to pY so I didn't think it could be part of a second recipe.
Have a good day !
