I am running into a bug near the beginning where when waiting for the main computer to load in the laboratory, I keep dying even though I have batteries in reserve. It happens when my energy reserves run out (still have 3-4 batteries at this point) and the main computer loads. They happen at the exact same time, so I couldn't tell which is the issue. If you are supposed to die when in the room with the computer as it loads, it is NOT communicated well. This is on the web version.
EDIT: I played longer and the computer does not kill you. I don't know why this circumstance specifically caused the game to ignore the reserve batteries. they seem to work now that I found a way around this seemingly one-off issue (I had to grind a mastery to make the timings line up differently).
