[2022] Saved games after Sept 8th patch

Major updates such as 1.7 are almost certain to cause issues with existing save games. They may present themselves immediately, or it may become an issue after playing for several hours.

After the 1.7 update is released, I'd strongly recommend using the Betas menu on Steam to roll back to the last 1.6x version before loading your ironman game.
