There is one last issue with wilderness imprints. Which is that getting an imprint pauses the game. Which is understandable since you want to read them. The problem is that there are 1100 of them. From my calculations it will take about 85 hours to get all the imprints. Which would require you to actively read and dismiss the event popup every four or five minutes.
Basically the mechanics now exist to afk and let the imprints be found. But the actual discovery interrupts the flow. It would be preferable if the process could run in the background and stack up events that you could read all in one go.
Edit: Also that 4-5 minute time is at 5,000x speed. It still requires an immense amount of in game years. So I wouldn't recomend anyone try to collect all the imprints until you get at 5,000x speed.
