Android: Liftoff loses open state too quickly

On my Android phone, switching away from Liftoff to another app usually causes it to unload. So, when I switch back, it loses the scrolling position I had left, which means I have to start again at the top. Other apps on my phone don't do this, and apps used before Liftoff don't get unloaded, so I don't think this is a memory usage issue.

Has anyone else noticed the same?
