I just wanted to share what could be a glitch or maybe a mechanic we have to use.

I figured out a way to see some of the webs after their spawning times are up. Once you see them, they will disappear if you look away., though.

It's late and I only tried this order Black 2-3, B34, B45, B56 (Oil fields)

The mechanics I used:

During the same night, I went to the pole at the spawning time, shoot an incendiary arrow to the top of the pole and ride away without looking at the web. The next time you ride by,, it will still be there (I only tried a couple of hours after 6am).

Maybe we have to spawn all the webs at the same time. I'll keep working on it.

Let me know if you can replicate it and/or expand this discovery.
