Hello, we’re back with another update for RimWorld! If you need to report a bug, or you’re having a problem while playing, please join us on the **[official RimWorld development Discord](https://discord.gg/MC6eYAHuPu)**.

Today’s update fixes several issues people were experiencing with Odyssey. This includes multiple corner problems where buildings through corners affected room roles, beds could become prisoner beds through corners, and enemies could set fire to your stuff through corners. It also fixes diagonal walls leaking room vacuum under certain circumstances, issues with player shuttles being lost to water, as well as gravship launches causing your electrical connections to scramble.

We’re also aware of a bug where quest shuttles incorrectly try to land on water, potentially causing them to warp into your buildings. We’re working on a solution - a fix for it is currently available on the Steam unstable beta branch!

This update should be compatible with all savegames and mods.

And if you’re enjoying Odyssey, consider leaving a review on Steam! Expansions don’t get a ton of reviews, and every one helps us out a lot.
