You can reset node spawns by merely accessing a other nodes.

More specifically, nodes spawn in pairs. Accessing one will respawn the oldest pair (There are 3 pairs of each node)

Why is this important?

Well, for Ephemeral nodes that are only available at a given time in game, this will be done to gain more attempts at harvesting from this special node.

Outside of that, you can check all of the "Blank" nodes (Ones that don't have the +1 gathering attempt, 5% HQ increase or 10% gathering rate effects on them) to fish for the random effects that are more potent (Such as +2 gathering attempts, +1 yield, +50% HQ increase etc) which can make harvesting collectables much easier (Especially due to you wanting to get the most out of your GP, given the CD on Cordials)

Actually, Ephemeral nodes are quite good. Specifically because if you gather collectables from them, they're worth slightly more than from regular nodes (But are harder to obtain good qualities of)

Which is noteworthy for trying to obtain Yellow Scrips.
