Okay, I finally figured this out. It was a combination of a bug and probably a bit of poor design. Currently when you leave the hab it automatically tries to top off both your battery and your oxygen from the hab reserves. If there is not enough of either to completely refill your supplies then it will empty out the reserves. When you left the hab it emptied out both, which if done at night like you did, will leave the hab with no backup power to run all the life support modules, so everything shut off. However, there was also a mistake in the code causing you to only receive 1/100th of the amount of battery recharge you should get for your suit. So you emptied the reserve battery, but it did not appear like it actually recharged your suit battery. I've fixed the bug and will have a Steam update patch available soon. That being said, I think I will prioritize the creation of a new datapad screen that will come up when you attempt to leave the hab which will allow you to choose how much oxygen and battery you want to pull from reserves before leaving. This should prevent you from accidentally causing all your systems to go offline when you leave the hab at night.

Thanks. I'll take a look.

Can I ask what version number you have in the upper left of the main menu?

Is it possible that you don't have any working tanks installed for either module? If you are able to, it would be good to get a screenshot of both the Diagnostic screen for those modules and the Habitat Status screen so that I could try to see what is going on. Thanks.

I figured it out. This was a bug with the saving and loading where the suit reserve battery and the habitat internal temperatures were not being loaded properly and were instead being reset as if you had started a new game. I didn't catch it because in my testing both the internal temp and the reserve battery were able to recharge/reheat before I noticed that they hadn't loaded correctly. In your case you were immediately impacted by the problem. Thanks for the bug report and this should be fixed in the next update!

Thanks for the detailed description. I'm going to see what I can do to investigate this, but your save files would be useful. I believe there should be an option to upload attachments here in a reply.

In the next release you will be able to use either WASD or the arrow keys interchangeably.

Glad to hear it. Thanks so much for helping to test this!
