Just published a release with a new default option, Simple Centrifuging, that replaces water barrels with liquid water in the recipe, and adds a fluid intake for centrifuges. Setting is on by default, and can be toggled off for the old barreling version. Hope this helps, and sorry it took so long. No luck on the pain management side unfortunately, problem is a combination of spinal and muscular, and that isn't something easy to fix. I'll be alright, it isn't harmful other than pain. Hope you enjoy the mod though.
