Resuming graph activity after it was destroyed crashes the app

[daniele-athome]

I'm assuming it happens because the activity is destroyed by the system due to memory pressure. Anyway here is the log:

Hello,

I ran into the same issue twice now, collapsing the data for the last week and second time around collapsing the past four days. What I figured was that the TSV file was last updated when I had last turned off/restart my cell. If you restart the cell you are using it should update the TSV file and back up your data. I am a mechanical engineering and my coding background is limited. hopefully this helps you.
