We just recently installed this mod to our pre-existing playthrough right around the time of starting to get into space travel.. Once we got to maluna and began trying to setup Advanced Boilers to process things involving Carbon Dioxide, such as steam, we could not get the ports of the boiler to ever output the carbon dioxide. the port that should output it turns into one of the various other outputs such as water and oxygen. It is impossible to get carbon dioxide out of anything or store it into a tank or anything. Please advise.. Do we have a conflict somehow? have you come across this?

Hm, Muluna is not a default part of this planet pack, so I'm guessing you either had it installed beforehand, or possibly enabled the other version of this mod that does include Muluna.

I can see many reasons why this might appear broken on your end, but an image might help, with Alt Mode enabled.

Since Muluna isn't part of this specific planet pack, I haven't run into this, but the Advanced Boiler does appear to be more complicated to route fluids from my preliminary testing. I specifically tested with the Advanced Water Boiling recipe.

The most annoying parts are that there three input/output pipes located adjacent to each other, with passthrough functionality, which means you have to use an underground pipe for the water input (or use an underground pipe for oxygen and carbon dioxide, or just use undergrounds for all 3 of those), and the steam outputs to a completely different side by itself.

Here's how it looks in my preliminary test:

Probably a cleaner example would have been chaining multiple of these together, removing the north-facing water pipe, and just placing more of these advanced boilers adjacent to each other going northwards, making sure the steam output pipe is always facing to the right (that would line up the rest of the input/output pipes)

Another important note is that I set the recipe before connecting any pipes to the machine; if you connect the pipes first, I'm not sure if they would connect properly, and you might need to 'empty' the internal pipe network of the machine (easiest way is to just mine it up and place back down, making sure the recipe is set before connecting to the fluid network)

If you do have things set up in a similar manner as the image I posted above, then there may potentially be a mod conflict with a non-planet mod. My guess is one of the pipe mods, specifically the one that prevents fluids from mixing, I think, since that one makes some sweeping changes to the fluid network.
