Add FixAirdropCrashPatch (!175)

This fixes the current issue of having an airdrop in the game causing a CTD after an extract.

There's still two caveats to this that I'm looking into:
- On the very next raid, the sky will still have the chaff from the flares in the sky, however these will have pink textures and take a few seconds to dissipate.
- On the very next raid, calling in an airplane with a red flare will cause the notification manager to spam messages about the airspace being currently in use even at the start of the raid.
