Weird, and definitely looks like a bug.

Hello Whitelight25,

In order for us to fully investigate this issue we need the following:

• Your last two auto-saves, and any other saves you think may help show the problem. Your saves are by default located:
  1. PC: \Users\[username]\Documents\Humankind\Save Files
  2. Mac: This is hidden in the Libraries folder. You will need to do an internet search to find specific steps for your OS. Once the libraries folder is revealed, they are in /library/ application support/humankind/Save Files

• Your diagnostics logs. These are time stamped, and any time you close and relaunch the game, new ones are started. Please grab all diagnostics logs related to the session you were playing where the issue occurred. These are by default located:
  1. PC: \Users\[username]\Documents\Humankind\Temporary Files
  2. Mac: This is hidden in the Libraries folder. You will need to do an internet search to find specific steps for your OS. Once the libraries folder is revealed, they are in user/library/ application support/humankind/Temporary Files

Thank you for taking the time to send us this report.
