- Fixed a crash at the shooting range.
- Fixed an issue where Rucker would not spawn in certain situations.
- Fixed an issue where the tranquilizer rifle would no longer shoot in certain situations.
- Fixed an issue in System Rift where the "Heat Sensor" strategy page would not trigger after loading a savegame.
- 'Hold E' to open Mission Objectives/Pocket Secretaries/Strategy Pages/Etc. are mapped to the TAB key by default. This removes the interference with 'Hold E' to drag bodies.
