I also have this bug.

Ah good to know it's not an isolated exception. I have so many mods I wouldn't otherwise know what the conflict was xD

yea me too, after loading a savegame the freezer goes to NANF, food says frozen but it spoils anyway

it's affecting the entire indoor area even those rooms w/o duct/vent connections.
opening doors to the outside world doesn't equalize temps.

I found i didn't have this problem when i loaded a game in the middle of a solar flare.
try turning off all your coolers before saving?

or just to be safe; only saving during solar flares, that's probably an easy enough fix for now

That's why I said that for use in a savegame you should remove the heaters/coolers

This also happened to me in a fresh game. I am trying to recreate it and see if i can figure out what caused it

this also happened to me.

too clarify, before hte update i destroyed all the duct coolers, the intakes and outlets and the piping and etc, and when i updated and re placed them all, it seemed to work, with the industrial cooler and all. now that i load up the save the temps are NAN.

I'll check that out

ok, thanks.

I'm also getting this error (except I'm using fahrenheit, so it's NaNF). Additionally, every time I load up my save game, all of the rooms connected to Smart Outlets instantly shoot up to about 600 degrees F, burning colonists and setting fire to furniture (see screenshot below). The temperature eventually settles back down, but the ducts still don't seem to function correctly -- the duct temperature is also "NaNF".

Interestingly, if you put a pawn in a room that is rated at "NaNF" (like my greenhouse, in the second screenshot, below), the pawn gets both the "burning up" and "freezing" mood effects, simultaneously. They disappear instantly when they leave the room.

Good luck!

Hello and thatnk you for the beautiful mod.
I experienced this NaNC problem too when I loaded my save today. Yesterday I played with the mode for several hours without any issues.
When I exited the game completely and restarted it from Steam it came back to normal. We shall see))
ok. it took the game about an hour to return to NaNC

@Assile: You are using a lot of mods! I'll need the output_log.txt to track down the issue.

@Everyone else: Does anybody of you have a save with olny RedistHeat installed and this issue?

Looks like there's is a null reference in the validate procedure for the industrial cooler & heater:

Exception ticking RedistHeat_IndustrialCooler1487232: System.NullReferenceException: Object reference not set to an instance of an object
at RedistHeat.Building_IndustrialCooler.Validate () [0x00000] in <filename unknown>:0
at RedistHeat.Building_IndustrialCooler.Tick () [0x00000] in <filename unknown>:0
at Verse.TickList.Tick () [0x00000] in <filename unknown>:0
Verse.Log:Error(String)
Verse.TickList:Tick()
Verse.TickManager:DoSingleTick()
Verse.TickManager:TickManagerUpdate()
Verse.Game:Update()
Verse.Root_Play:Update()

(Heater has a similar error). By adding a few logging bits to the code and rebuilding the dll, i was able to determine the the compAir variable is null and this is the line that causes the error:

if (compAir.connectedNet == null)


When looking at the heater and cooler after loading a saved game, they are no longer connected to the network (pipe overlays missing) and there's no button on them to switch between upper and lower channels. Exhaust ports are the same, but they don't generate the null reference error. Saving/reloading once the issue occurs, even after deleting all the coolers/heaters/ducts/etc doesn't fix the missing button, and any newly placed industrial coolers or heaters won't have the buttons either.

I'm using several dozen mods, so I can't provide a saved game unfortunately.

that's the problem in my debug world I can save and reload without problem, so this looks like a mod incompatibility. If you post the output_log.txt I may be able to find out what's happening
