Hello, I am currently struggling a problem with yapb while waypointing on zombie maps. After loading bots joining the server I got these error logs from console and these errors are overusing server cpu and leads to a crash;

[A* Search for bot "*" has failed. Falling back to shortest-path algorithm. Seems to be graph is broken.]

Couldn't find any solutions on the net, it seems I am missing a basic instruction. I've already inspected non-buggy maps and their waypointsi I couldn't find the part I am missing. Any helps are appreciated.
