 * Skies can now be drawn horizontally linear by enabling the new `r_linearskies` CVAR, which is `off` by default and when vanilla mode is enabled.
 * The automap is now always updated when the `r_screensize` CVAR is changed while it is open.
 * A bug is fixed whereby any player movement wouldn’t be canceled when opening the automap and the `am_followmode` CVAR was `off`.
+* Savegames that were saved in maps `ExM10` or `ExM11` no longer crash when loaded.
