Navmesh appears to be generating how it should but enemies are not moving. Settings have been added for navmesh invoker. See attached BP for the enemy character, it has a Navigation Invoker already attached. Also here is a video of it in action: Caffeinate - Troubleshooting AI issues - YouTube Any help would be greatly appreciated!
I was able to figure this out but wanted to pass on the solution so hopefully this will help someone else as well. Followed this tutorial and it worked perfectly - Unreal Engine 4 Tutorial - AI Random Movement/Chase Tutorial - YouTube Once created you can easily add other AI elements to this.
Add navigation invoker component to the tile you want to spawn
also look for how to setup nav invokers it’s easy to find on youtube
