Patch v0.7.9.5.3

This one feels a little big to just call a hotfix, so I'm calling it a patch instead because it fixes a whole bunch of issues. The majority of these are directly thanks to all the bug reports sent in by player Samildannach -- big shoutouts and appreciation!

Changelog v0.7.9.5.3:

• Fixed several issues with Power Plant cave exploration

• Fixed crashes at the end of certain side job missions

• Fixed issues with Local Problem side job

• Fixed crash when ambushed while returning to Esper

• Loading into interactive story segments should no longer cause buttons to become unresponsive

• Game now autosaves after side job completion

• Game now creates a backup of the previous save when saving

• Fixed Shadow NPC sprite disappearing when reloading on certain story segments

• Fixed last line getting cut off on side job mission briefings
