Sylph Cave fix
Reminder: If you haven't downloaded GameAssets.zip, you will need to do so via the version 1.0 release.(https://github.com/gameboy9/FF4FalconDive/releases/download/1.0/GameAssets.zip) It's not included here out of respect of taking up unnecessary space on GitHub.
- Fixed a minor bug where you can fight the Sylph Cave boss multiple times and get its' reward. This bug is minor because multiple copies of a reward, including Nothings and Crystal Shards, do not actually mean multiple copies because of how Nothings and Crystal Shards are actually counted.
