First of all I'd like to thank you, RoverDude, for this and other amazing mods.
Not sure if I found a bug or I'm doing something wrong: It seems that during catch up recyclers aren't taken into account.
Basically I put 3 kerbals, 500 supplies and 3 recyclers into orbit, when I start the recyclers the supplies countdown increases to 53 days, as expected.
Then I time warp in the tracking station for 5 days: 48 days of supplies left.
But when I get back to the vessel, there are only 41 days of supplies left and 162 supplies were consumed, the exact amount for 3 kerbals during 5 days and no recyclers working.
