In order to move on the map, the bots follow an invisible mesh, called the NavMesh. If this mesh is not computed when the map is loaded, the bots won't move, since in their point of view there is nowhere to go. This variable forces the game to compute the NavMesh.
I spoke a bit too fast when I said it was a bug. When you use autonomous bots on a map, the NavMesh will always be created when this map is loaded, since the mode doesn't know if there are such bots. However, not calculating the NavMesh makes the map load faster. The point of being able to set this variable at False is to be able to use a map without being forced to compute the NavMesh (and thus avoiding an unnecessary increase of the loading time), for instance when you want to play on maps designed for a mode that use BotPaths, while your mode doesn't need them.
I don't know if being able to control the computation of the NavMesh is really an important feature. We will see in the future if we keep it this way. Maybe an automatic computation when the map uses bots (regardless of their nature) would be more comfortable, but after all it's just one line in the script ^^ I'd like to have the opinion of the modders and mapmakers on that topic.
Anyway I edited the documentation.
