Jungle Adventures Takes too Long for Market Vendor to spawn items needed

@inniyolk It absolutely does take ages to get the jungle remedies, it's quite frustrating.
One thing you can do is max the Selvadoradian Culture Skill and that enables you to start buying some of the essentials while talking to any vendor using Buy Supplies and Secret Wares. Machetes and Waterfall in a Bottle are some of the items you can buy in bulk that way. That's handy when you lose a lot of machetes in the jungle.
Once you've bought some items have you tried copying them by placing them in a room and saving it to your library, then (once you're home) placing the room a few times? That might work. I've stocked a retail lot with jungle remedies using the Get to Work pack cloning machine and Realm of Magic Copypasto spell so that my Sims can shop at home before travelling. I was fed up of queuing for 1 single Guzmania Pollenis flower!
The stalls do change a few times a day and some of those items can also be found/caught while fishing and exploring the jungle.
With Jungle Adventure, it takes a lot of trips because if you haven't noticed the jungle changes with each visit. Different jungle gates open on different trips and the temple changes every visit too, it has several types of temple to show you. On all of those trips you start to accumulate remedies and essentials. If you have high fitness, fishing and (I think) logic skill you need less of the jungle essentials as you travel. When arriving at a gate it might give you an option to use your skills instead of an item/remedy to complete a task and travel through the gate.
But it would be great if all items were available more often. It's always Drake's Fire Quencher and the flower for me!
