Hi, the team )
No, restart didn't help, I had to start a new game. But don't worry about it - I wanted to do it anyway after finishing to try some other dialog options.
Thank you for answering, I'll try to keep my eyes open for any new unusial issues.
Good luck with any further ideas! When I see a project so big and ambitious made by a tiny team it gives me hope for a brighter future where lots of games are suppose to really tell something, not just making money out of popular cliches.
