Hi,

When I made the Coolbag mod I met the same problems as you do now for solo games and when multi arrived for B41 the same multiplayer problems. I solved them with a crazy amount of time and complexity management.
I let down many small details like respect of thermodynamic on the way .

Here are the main problems :

• Food aging process does not care about the temperature of the bag it is in. This is due to Food.java class looking for the OutermostContainer to extract temperature information.
  
• In multiplayer food aging process is done on the server side.

If you want to check the efficiency of food conservation by your mod:

• compare the rotting time between an food item in the coolbag and an item in a random container.
  
• use eris food expiry mod but only for indication in your test process, do not use is as final comparison info (never use any mod for that, only vanilla data).
  
• play solo and use debug time increase. check MP once solo is fully operational..
  
• use bacon bits, they rot very fast.

For now in a solo test (vanilla B41.68 + Eris + Smokin' Joe's Cooler), aging speed was the same for:

• a bacon bit in an organ cooler on ground with 5 large frozen ice packs.
  
• a bacon bit in an organ cooler equipped as secondary with 5 large frozen ice packs.
  
• a bacon bit on ground.

If I made a mistake I am sorry.

Your models are awesome by the way.
