In case you didn't see, we just released a massive patch for FortressCraft including a variety of new features including the workshop, where you can build your own blocks, and server ratings and rewards. For a full list of new features, click here.
As there were so many new features put into the game, there are inevitably a few bugs which have been introduced, and we are working hard on a bug-fix patch which will be put into peer review as soon as possible. For a complete list of known bugs and workarounds please click here.
