Added an internal save backup system, which acts as a safety net against silent write failures (AV locks, steam cloud, crash mid-write, sleep shenanigans, etc), to prevent those rare save losing cases.
Additional fixes for the bonus PP from previous hotfix resetting.
Reduced the costs of Railguns and Railgun Capacitor a bit.
Further reduced the costs of Nuclear Research and Air Strike, and increased the chance per tier of Air Strike.
Added the ability to right click on the mountain to toggle Eternal Feasting (auto-clicking) ON/OFF.
