perf: Add path height correction on world load (#1178)
* Add path height correction on world load

* Increase height because Nexus Tower is tall

* Update height checker

- Only go up and down, do not deviate from the point you are on
- As a backup, use the nearestPoint on the nearestPoly, should detour be able to find one.
- Add a debug assert to fail the program should toReturn differ from nearestPoint[1].

Update dNavMesh.cpp

Update dNavMesh.cpp

* Fix if condition to actually return the value...
