Fixed duplex rear stairs causing bots to clip through them while stepping up.

More minor changes to props;
-updated fire escapes, they are now prettier and easier to navigate
-widened all usable doors to 2m: this allows me to delete as many pathfinding links as possible, since EA 27 seems to once again be highly unstable around links.
-other tiny misc changes

In terms of structure and layout, this map should now be finished, as in, "no more big changes", but there's no telling how many more tiny aesthetic tweaks i will make if i feel like it.

First Update With some minor prop changes and edits to flow;
-Added extra bushes and trees
-Allowed Duplex and Greenhouse to attack eachother, making for a less stagnant battle aroubd the greenhouse.
-Other minor miscellaneous prop changes.

It is still possible for one team to get crammed into and trapped at Road. Hopefully the advent of scripted missions will allow me to do some cool things with scripted re-enforcements in such a scenario.
