Hey kimitoosky, thanks for reaching out, welcome to forums and sorry to hear about the issues you ran into.
1. In regards to not being able to proceed with Age of Exploration recipe, I can confirm that this has been brought up to our development team, however in order to aid us in further review and for reproduction purposes, is there any chance you could provide us with your save file? It's by default located in %userprofile%\Documents\Anno 1800\accounts
2. As far as losing your save goes, I am not exactly sure what led to it however if you do not have it saved in your save file folder then I am afraid we will be unable to restore the progress you've made on your save file you're referring to.
Should you have any further questions, let us know!
