You probably aren't configured to sell back items, or pick up gold or potions during the run. Full rejuvs are dropped by nearly every unique minion every time, and gold is very plentiful if nobody is using pickit around you. There are also many super healing and mana potions dropped if you wish to configure those to be picked up as well.
Also I once saw a bot advertising on west once "If you wish to keep his run going drop some gold near me in the throne room so I can buy potions and tps" or something to that effect.
also remove the ; in front of the potions you wish to pick up in the potions.nip file in /settings
