Maps: bot gets full inv, uses all portals at once (0.56j)

[Daskoobas334 3]

Hi there,

 

Been giving mapping a go today. The bot would do really well, until it fills its inventory up and then it would summon a portal, use it, go back to hideout, identify items and then use the portal back into the map. Once in the map it uses the portal back into the hideout. It does this until all portals are used up and then it goes to sell items and then fetches another map.
Why is it doing this constant portal use to waste the maps?
