in release notes: Unreal Engine 4.13 Released!
it is said: “Made Simple Move To Location/Actor reset velocity only if the agent is already at goal.”
BUT I found that everytime that function is called it restarts velocity back to 0 and than it starts accelerating to maximum speed.
Maybe I am wrong can someone check that please, maybe I am wrong.
Yes, that is exactly what MoveTo does now (in 4.13).
When MoveToActor/MoveToLocation is called, if another move request is running, it gets aborted; in the abort process, character velocity is reset.
I believe it is not a correct behaviour, maybe it’s an undesired side effect of recent engine modifications.
OK Thank you for you answer it was very helpful 
but now I have new problems, so In past I would set timer on custom event TrackPlayer (that has AIMoveTo inside) that would tick every second, so if player wasnt on nav and than he steps onto nav mesh with at most 1s delay TrackPlayer would be called and controller would track the player. Now in this new version of unreal[4.13] I cant set timer on TrackPlayer as you point it out ( everytime it would reset velocity), but if I cant set timer, than if player isnt on nav mash when TrackPlayer is called ai controlled actors wont come for player. Example: Player is on nav mesh and he is runing away from enemyai. Player steps of nav mesh enemyai is not following. Player steps again on nav mesh enemyai wont follow because no one is calling TrackPlayer function.
But if AIMoveTo would behave same as in last version, than I could set timer on event ( let’s say every 1s), than with most 1s delay AIMoveTo would be called, and enemies would continue to chase player.
Can we somehow solve this kind of a problem in new version of unreal?
I dont think that this answer is satisfactory. It is a step in right direction, but I still have a problem to solve!!!
Hello,
This is currently a known issue: Unreal Engine Issues and Bug Tracker (UE-35852)
Thank you for your report.
Have a great day
Thanks, that is helpful is that bag going to be resolved in next patch and if does when the next patch is going out?
There is currently not a timeline for when a fix will be released or for when the next update will be released.
You can vote on the bug on the public tracker in order to keep it in your list so you’ll be able to check it periodically for updates.
You can take the velocity from the character movement, do your AI MOVE, then set it back right after.
