I am playing KSP x64 v1.3.0.1804 with Kerbalism and USI exploration pack in sandbox mode. I have launched an Otter crew cabin into orbit around Kerbin with some batteries. The nitrogen usage is normal at first, but if I disable the habitat function, and then enable it, the nitrogen levels deplete very quickly, about 1 unit / s.
Mods:
Community Resource Pack v0.7.1.0
Firespitter Core v7.6.0
Kerbalism v1.2.9
Module Manager v2.8.1 USI Exploration Pack v0.8.1.0 USI Tools v0.9.2.0
I created a clean KSP install and only installed Kerbalism and USI Exploration pack from Ckan, including the dependancies.
Steps to reproduce:
Go into VAB, place the Stayputnik as the root part, place an Otter Crew Cabin below, and 4 x Z1-K batteries below again. Stick a Communotron 16s on the side. Save and launch. Press Alt-F12, select Cheats, select Set Orbit. Ensure Kerbin is selected and set the Semi-Major Axis to 2686750 and select Set Orbit Close the Set Orbit Window. Right click on the Otter Crew Cabin and leave this window open. Timewarp for a period of time to ensure that the Nitrogen usage is normal, about 1 unit every 30 minutes of game time. Disable the habitat. Once disable, enable the habitat again. Nitrogen usage is about 1 unit / second.
If I disable the Pressure control the nitrogen usage stops (expected). Starting pressure control the nitrogen usage starts again. If I launch a new vessel and only disable and enable pressure control the nitrogen usage remains as normal. it only happens when Habitat is disable and enabled.
Is there a way after I disable the habitat and enable it to return the nitrogen usage to normal rates?
[edit]
Actually just did another clean install and only installed Kerbalism and module manager, and did the same test using a Mk1 inline cockpit. I had to configure pod for pressure control, but when I disable and enabled the habitat the same issue occurred on the Mk1. The nitrogen usage skyrocketed after enabling the habitat.
