I have had some nodes fizzle out in as short as 45 minutes eorzea time. I've yet managed to collect collectible even once due the window popping out when I'm still figuring out how the system works. While I admit the shorter time frame is good for the purpose of limiting when you have to be on the node, please make it to not fizzle if it's already opened. That quick fizzle is making it unplayable and feels just a slap on the face.
