* Possible fix for rare bug regarding orbiting bombers at a target.
* Added safety mechanisms around Animation Slider setting that should keep users from experiencing a Hang from various city, invasion, or movement animations. (Possible divide or multiply by zero existed.)
-> This is guesswork to address recent bug reports.
New:
* Added 'Challenge Mode' option to Normal and Easier so players can experience the 'higher pressure' of harder difficulties, without the difficulty actually increasing directly.
Minor:
* Corrected some text regarding critical damage tooltips
* Protect City missions will no longer spawn Fortified mod
* 'Fortified' Admiral will no longer potentially have Protect City missions
* Increased max plane speed for long ranges
* Skirmish/Surrender/Campaign loss generally increased XP
* Increased 'horizontal preference' for city generation (should help position them better on average.)
