I'm sorry that you've run into that crash with VV4 Lite. Unfortunately, we have not been able to reproduce this crash on any of our test devices (and we have tried many times). As a result, we have not determined the exact cause of the crash, although it appears to be related to the population limit in the free version.

The free version of Virtual Villagers 4: The Tree of Life is limited to a maximum population of 9 villagers, and it appears to be crashing after it reaches that limit. Until we are able to find and fix this bug, you should keep the population of your tribe at a maximum of 8 villagers to avoid the crash (and make sure that no villagers have a checkmark next to Parenting on their details screen, so that no baby villagers are created without your direct involvement).

If you are unable to open the game at all, the issue may resolve itself and allow you to open the game again once the population has dropped below 9 villagers (due to aging and attrition). If this doesn't happen, the only option may be to delete and reinstall the game. Please note that everything in the game will be deleted, and you will need to start all over from the beginning.

This crash only occurs on the free version, and doesn't occur on the full, paid version of the game. We are very sorry for the inconvenience this causes, and we recommend the action described above to avoid the problem until such time as a fix is available.
