Update 22 is now available on the Test Build branch. There are still more changes in development for this update, but I wanted to get some initial feedback on the content so far.
Click the following link for more details:
The optional Test Build branch is for testing the latest features before they go live to everyone. As it is a testing version there can be more bugs/issues than in the normal version. If using the Test Build branch, please report any issues you encounter or any feedback on new game play mechanics. Your feedback and/or reports will help to ensure the final version is the best it can be.
