- Added: Backups of the Venue.bin file are created in the "[YourProject]\backups\" folder when saving. See Options for Backup Count.
- Improved: Interface no longer prevents user interaction (momentarily freezes) whilst flagging grounded objects.
- Improved: Flagging end node of a joined track as Grounded will also flag the other node of the joined track.
- Improved: Walls are flaged for calculation less often (more efficiently).
- Improved: String Objects that are Grounded and Tilted use faster hit-test.
- Improved: Google Fetches height data, then updates in larger batches to avoid triggering the recalculation too often.
- Fixed: Rendering of non-AC Terrain when Target set to AC would cause some rendering artifacts.
- Fixed: Couldn't open any Venue after attempting to open one with a missing texture.
- Fixed: Grounding Node for String Objects and Walls wouldn't take effect until next calculate.
- Fixed: Prevent project from being create with non-ascii characters in the path. Autodesk FBX SDK can't handle them.

- Fixed: Allow Venue to load when String Object is missing.
- Fixed: Straight Wall with multiple Surfaces not calculating correctly.
