Virtual Villagers 4 Tree of Life keeps crashing

Keeps crashing and freezing when I move a man onto a woman or a woman onto a man to go indoors. I am using BlueStacks (Android) on my MacBook Pro. I want to reinstall app but I don't want to lose my game play. How do I save/backup my game play so I can reinstall it?

As far as i know, they don't provide support for emulator players as the games are not made for playing at emulator.
Maybe you can try mac version?

The free version of VV4 on Android will freeze and crash when the population attempts to grow above the limit of the free version.

As Hydra14 correctly stated, we don't support emulators. The best resolution for your problem would be to play the Mac version of the game.
