This is a bug I’ve discovered 5 months ago. It was since patched on iOS/Android (1.3.2)

What this bug is:

This bug will prevent any nutrition depletion penalties from occurring when re-entering the lair early.

How to perform this bug:

To perform this bug, hold interact to enter the lair. Before you have entered the lair, begin to hold the PAUSE button. Once you have loaded into the lair, let go of PAUSE. From there you can press “Main Menu” and then “Continue”. That’s all to it!
