Greetings fellow rulers!
This patch is just a small one that just fixes two annoyances.
If you have Workers stuck on a Festival in your save, they will be free once any Festival finishes. For the Prosperity, you might need to wait a few seconds, but then generation should pick up again where it left off.
Should you still encounter any of these two or different issues, please let us know and we'll take care of it as fast as usual :)
