+* “SIGIL” can no longer be selected in the episode menu if *SIGIL* isn’t loaded but *SIGIL II* is.
+* The author of the current map is now displayed by the `mapstats` CCMD if known.
+* A bug is fixed whereby the corpses of monsters could become solid, blocking the player’s path, in some rare instances.
+* Minor improvements have been made to text autocompleted in the console by pressing the <kbd><b>TAB</b></kbd> key.
