Ostranauts v0.9.5.9 is now available on Steam, and your clients should be updating shortly.
This is a hotfix to our recently released "Wear and Tear" update, and includes some fixes and changes we felt were important to release as soon as we could. Plus a few changes unrelated to the next milestone which seemed ready to release.
Note that we are still working on the next (Slots/Wounds) milestone, as well! But those inventory and wound changes still have some work to be done before they are ready for players to try.
