(svn r22747) [1.1] -Backport from trunk:
- Fix: Some corrupted savegames could crash OpenTTD instead of showing the 'savegame corrupted' message [FS#4717] (r22737, r22736) - Fix: Triggering NOT_REACHED when playing with a NewGRF that supplies genders/cases for a language that was not installed [FS#4718] (r22735)
