This update continues to focus on getting the latest build ready for Alpha 6. There is still a major focus on removing the bugs on operating systems that have been causing save issues.
One of the major issues in terms of crew members floating into space was addressed with this latest update so there should be a great deal of improvement with that. In the event this is still occurring please let us know as this is actively being worked on.
Overall this build adds a great deal of polish to the current systems in order to make way for the next major update.
The full patch notes can be found here!.
The layering system used in order to get the 2D world to appear correctly has been overhauled in order to make future updates a bit better. You should see a lot less incorrect layering in terms of shadows, and stairs etc.
