Navmesh baking stuck on "Exporting Tiles" with no progress.

After updating to Unity 5.4.0f3 I can no longer bake navmeshs. Or the navmeshs might be taking REALLY long to bake. Previously I could bake terrain in a few seconds but now when I press bake if just flashes "Exporting Tiles" at the bottom right rapidly with no progress on the bar.

What I've Tried:
- Insuring the object I am trying to bake is set to navigation static (set everything to static just to make sure.)
- Set the Navigation Area in the baking window to "Walkable."
- Tried adjusting the agent size and even looked into the Advanced tab and messed with the "Manual Voxel Size."
- Attempted to bake a navmesh in another Scene - didn't work.
- Clearing the GICache.
- Waited around 2 hours for a simple 1x1x1 Unity cube - still did not bake in my project.

I haven't tried another project yet - I will allow it to bake overnight. I really hope someone can figure out what I'm messing up. I've been working on a game for almost 2 years and it would be a serious pain to have to port it out into another project or use another pathfinding solution.

 

Ok so apparently it does work. It just takes way longer than it did before.
I'm running

Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz

Video Card
NVIDIA GeForce GT 650M

RAM
8.0 GB

Operating System
Microsoft Windows 10 64-bit

These are somewhat interesting wait times. I think they updated the navmesh with new features in 5.4 - just give it some time and it does build.

 

Thank you for following up with your own post! Good to hear, I have a huge scene that I'm trying to bake right now, and I was worried that it wasn't going to work

 

Me too, thanks!
