Known Issues

Releasing as an add-on means that our code changes are not included. Missing code means that the following features are not working:

Fire, smoke and explosions do not trigger panic events in the hangars.
Zombies do not crawl all the time in the orchard.
Farm house mob does not spawn in the far side of the woods.
Covered bridge does not collapse with explosions.
Burned forest area is missing wandering fires.
The burning forest section has a burn trigger that stays on too long. If you move quickly you'll take burn damage.

The dam spawn room is missing health kits and weapons.

The elevator models have an offset origin in the dam. Players can still get on and use them, but they are invisible and wall collision is missing.
