Hey there,

First of all, love the mod. I just wanted to let you know that several of the vents/coolers listed do not have prerequisites attributed to them. So, when starting as lost tribe the "immersion" is sort of broken with several of the HVAC units allowed to be built, but with no electricity/etc. I took the liberty of modifying the .xml files for each part to include what I consider the proper prereqs.

• All small/medium HVAC units, and vents now require Air Conditioning. This doesn't apply to the stock vent, for some reason that will not modify (I'm new to modding).
  
• All other require Temperature Control, this includes your ducting/piping.
  
• All thing.xml files have been updated to Version 1.1.

Are you interested in updating your mod to be lost tribe friendly? I don't know the best method to share the three .xml files, so a little help with that would be appreciated.

Thank you again for the mod.

Edit: I've play tested and all is stable.
