The Red Jungle has gotten a full foliage overhaul, aside from the bigger trees, but the smaller trees that can be cut down have been overhauled.

This may mean trees popping up in your factories, but you should be able to take care of it.

There's also been some mild landscape sculpting to facilitate better pathing through the jungle again.

You'll see that this is a common theme throughout this update, a lot of, like, roads and pathing and things like that, and the Red Jungle is definitely one of these areas where that has happened.

This shouldn't have any major effect on existing factories, so you should be safe here if you've got stuff there.
