Random crashes when using Character: move to point

SkyTree

Simple, create an interaction, marker and object.
Add player component to your object.
In the interaction set your character/player to move to your marker.
Execute it and wait few seconds. The crash is random but very very often, alsmost all the time.
I get this crash error:

transform.position assign attempt for 'Slab02Found' is not valid. Input position is { NaN, NaN, NaN }.
UnityEngine.Transform:set_position(Vector3)
AC.Char:MoveUpdate() (at Assets/AdventureCreator/Scripts/Character/Char.cs:836)
AC.Char:_Update() (at Assets/AdventureCreator/Scripts/Character/Char.cs:426)
AC.Player:_Update() (at Assets/AdventureCreator/Scripts/Character/Player.cs:163)
AC.StateHandler:Update() (at Assets/AdventureCreator/Scripts/Game engine/StateHandler.cs:318)

Before the latest update I used 1.47 and it was fine.

Not so simple, in fact.  Following your steps produces no such error for me.  What does your Settings Manager look like, particularly the Movement settings?

All managers settings. Hope this helps.

I'm afraid it doesn't.  Please place a problematic player/NPC in a test scene that shows this off, and PM it to me.

Sorry, but the problem persists using AC 1.50a  Unity 5.2.4f1

Re-post the Console message in full - it may be different this time.

SkyTree

Yes, you are right it is a bit different this time. Char.cs: 841
I used the same scene I PMed you.
Now using Unity 5.2.4f1 AC 1.50b

I can't recreate it - what once gave an error doesn't any more.

If you're up for it, you should be able to debug this yourself - the issue is that the variable "newVel" in Char.cs is being divided by zero - thus turning the newVel into infinity.  It's set in the MoveUpdate function, and you can see on line 782 that there's a check in place to ensure this doesn't happen.

Since the issue seems unique to your project, try inserting Debug.Log commands to find out at what point this occurs.

What Unity version do you use?
I have uneasy feeling all the new troubles come from Unity's version that I updated.
I usually don't have any problems with AC but since the update from AC 1.47  and Unity 5.1.1f1
several things have been f up.

ChrisIceBox

I try to keep on top of all of them.  I tested your scene in 5.0.1 and 5.3.1.

SkyTree

Ok, I think the problem is solved and sort of isolated.
I just simply copied my Manager's settings movement from the old AC to the new AC, which on update were changed. Though I loaded my old managers... but there are new features there so it might have changed them or affected somehow.

 However if the settings are different then Character objects must have Deceleration greater than Acceleration in movement settings of your Character object. And if for some reasons after you will get a Null object error, then you must create a navmesh 2d and add it to you Scene settings in Scene AC tab by default, and stretch it wide so it covers all your charcter objects and markers.

What a  journey...
I will never ever update anything in my life
Thanks for your help.
