OK figured it out. Have to start a new save for it to be read in. Even with just those 2 it didn't work so on a hunch tried a new scenario and it was there, even after turning all the other mods back on. It's a base game limitation not a mod issue. At least if anyone else has this they will know what it is. Thanks! :)

To clarify, you're saying that when you load that list of mods, the Combine reactions in the refinery's Reactions List are not appearing? I've tried to recreate this using the list, but it's working just fine. Do me a favor and load up only Split Human Waste and Combine Tanks and see if the problem persists.

Didn't say anything was conflicting when I added in Combine after the update. Total I have is Time to Sleep, Split Human Waste, 3x More Power, Barrels Storage, and Extra Items 2.0 along with this one.

Not sure what would be causing this. I've retested with only my script and in combination with Split Waste and in both instances, the Combine reactions are listed. Are you getting any other conflict or some other error on loading?

I don't find the refinery option on either the small or large refinery in the list of options.

Fantastic! Great news and really appreciate the work you put into this

Okay, I went ahead and updated the scripts and it should play nice with Split Human Waste now. It's only modifying the Synth_TKOM_Z_Base script, as I excluded all of the other cfglist files from the PAK. This should stop the conflict with Split Human Waste, but I can't guarantee any other mod that comes around that alters this same file won't mess things up. Sadly, this is a big limitation of TKoM's mod system. So, keep me updated of any other conflicts that pop up and I’ll try my best to work around them.

This reprots a conflict with the Split Human Waste mod. If there was a way to solve this so both can be used it would be great!

Very very nice Idea. The problem with this "used" tanks sucks. Thank you for solving this.
