Version 2.1

* Collision on the large main floor should now be working more properly

* Numerous "out of map" areas that were previously accessible by means of clever movement have been blocked off and can no longer be reached (sorry jumpers!)

* Several Zed spawn areas have been fixed, preventing them from getting stuck (hopefully)

* Lightmap resolutions that were previously way too high have been greatly lowered on many background elements that don't benefit from them. This is a minor optimization that has reduced the map file size considerably.
