Error on list querying

Hello,

I got a strange error in the model below.

agv-parking.fsm

As the photos showing, there were 4 tokens pull same one agv if I set query order by distance.

Software Version:

FlexSim 18.2.2

Change your puller on your "Pull AGV" activity to token rather then token.item.up, this seemed to fix the problem and the model seemed to run fine after that without 1 AGV grabbing all the boxes at once.

If I change puller from token.item.up to token, the distance field in list can't be calculated correctly because destObject is token.

I created a new field in your list called "Tokendistance" which gets the distance between the AGV and puller.item.up. The issue before is that a token only pulls 1 item, but the queue which you were referencing as your puller can pull as many things as it wants from a list all at once.15061-agv-parking.fsm
