The burrower stalk is a unique localized resource that spawns, takes one to two days to grow, and then when you harvest them they'll despawn and re-appear somewhere else. While I've never seen one, it's easy to admit it's a great idea and a good fit for Haven.

I think it's fair to say we should have more of these moderately valuable, location-shifting one-off harvestables. Then when they despawn they just enter a global pool, and then respawn again somewhere else. If it's only there for a little while and then shows up somewhere else, it makes it possible for hermits and smaller players to find, rather than only big factions and bots, and harder to camp when they're always moving around.
You could make them only visible for end-game foragers with hundreds of perc x exploration, which you identify and it tells you how long til bloomed/grown/ready, etc, like normal localized resources, but requiring a higher exp x perc means you can't just bot-camp them as easily. Makes them more like a super high tier foreageable and having them move around makes them more fun than the static, un-moving localized resources.
There's a lot of things you could spawn from there. They could give:
Gildings
Curiosities
Food/ingredients
Combine multiple into 1 of the bigger ones (like guano and rock crystal)
Shard of meteorite?~
Other fun items!
Since this is just a request for more content which is probably in the pipeline anyway, you know, do with it what you will, no biggie. Love Haven btw ❤ :3
