Ah, yes. That makes sense.

I can think of a way to get around the pausing:

Every tick is a set number of seconds (5, at the start of the game), and there's already a system in place that tracks how long "Away" mode was active

So, when "Away" mode is deactivated, temporarily set the tick length as low as it will go (most likely a single frame) for as many ticks as it was active before resuming play.

This should allow things to scale in the same manner as if "Away" mode was never activated, because all of the math happens while it *isn't* active very very quickly.
