Go to Quarry Mill.
In mesh manager:
Under GeneralSettings load the existing navmesh.
Under Editor check 'Show Triangles' (so you can see where it's adding and you know it'll meet up).
Fill in 'New Meshfile Name' with something, like "20-30 quarrymill fates".
Check 'Record Mesh' and run all the way to wherever the existing navmesh is and make sure your newly recorded stuff meets up with the old stuff.
Stop recording.
Hit the 'Save NavMesh' button.
Back under GeneralSettings, load your new navmesh and you should be set to go.

This works great unfortunately adding new mesh lags the helllll out of my computer and crashes me, and my computer isnt bad. i5 2500k OC to 4.9 ghz, 16 gb 1333MHZ ripsaw ram, 128gb SSD, 1tb 7200 rpm HDD, SLI GTX 480s, z68 mobo.

This bot is alot more stable on my desktop than it is on my laptop, my laptop crashes regardless of adding meshes or not and its an i7 3740 3.4ghz, 8gb ram, 7970m, 128gb ssd, 750gb 7200 rpm hdd

not sure whats going on.
