I subscribe to subj event, and surprised for minumum 2 times calling it for simple path task wManager.Wow.Bot.Tasks.GoToTask.ToPosition(new Vector3(-5470.455, -2890.753, 350.0887, "None"));

[N] 06:56:21 - [Path-Finding] FindPath from -5466.455 ; -2879.753 ; 350.0887 ; "None" to -5470.455 ; -2890.753 ; 350.0887 ; "None" (Azeroth)

Isn't should be once?

Hello, 

It's going to be complicated to solve this problem without having all the code.
Do you run your code several times (several threads)? You stop it well (when the bot is stopped).

Just ran it in development tools window for clean test.

Ingame it throws sometime 4-5 events for one ToGo point during usual questing or gathering or any else pathing.

When I run 

wManager.Wow.Bot.Tasks.GoToTask.ToPosition(new Vector3(-5470.455, -2890.753, 350.0887, "None"));

in dev tools I get only one pathfinder call.

If bot don't found path, in some case there can call pathfinder server several times.

Yeap, with other charachter's position it runs once o_O. Ok nvm then
