startup crash, the "matter-to-water" normal recipe fluid input needs to be above 0:

this seems to be the line to blame, unfloored it amounts to 0.5 for matter-to-water, but since fluid is a decimal it shouldn't need to be floored right?
(though looking at the code not-flooring just that one might cause some inbalances so i'll leave it to you, just know that this currently refuses to load.)

I deleted that entire for loop (I am basically only using the mod for the underground pipe/belt lengths) and the mod loaded on 1.1.101 for me.

Also I pinged larken on discord about this, he's said before he doesn't really check the mod portal, though I'm guessing he does probably see github. No response yet.

after changing the code the mod works but there is a problem with the laboratory more in this thread

unfortunately without this mod I would have to build the space base again
