Version of Engine 4.20.3. macOS Mojave. Troubles with project launching.

[SteadyCoder]

When I am trying to build the project from the branch 4.20. It start to build, than throw an error that failed to compile. The error seems to be coming from STrackerBot.cpp. Can't find "NavigationSystem" and "AI/Navigation".

Checkout your navigation system settings or share a screenshot.

I had the same issue on Windows (4.23.1)

in STrackerBot.cpp...

change:

#include "AI/Navigation/NavigationSystem.h"
#include "AI/Navigation/NavigationPath.h"

to

#include "NavigationSystem.h"
#include "NavigationPath.h"

Change line 119 from UNavigationPath* NavPath = UNavigationSystem to UNavigationPath* NavPath = UNavigationSystemV1

in CoopGame.Build.cs

Then add NavigationSystem to module names.
