After a certain period of time in the game, I get stuck on the 'responding' response. Also I can't save file. Are these a general problem or what should I do to fix them?
That is a issue, that I the developer have to fix. The new AI chat system is a new feature in a project that still in development. It's new tech that has not been fully implemented in a sandbox system before. I am working out the issues with it and implementing a save feature with in the next build.
