I don’t know much about the inner clockwork here but…
In my experience, I’ve found that it seems like anom spawning have a pattern linked to the day of the week.
This may sound crazy, but it is what I’ve found and checked many times with same results.
Weekends tend to populate a majority of hack sites, for example.
Some may say that yes, it is because anoms are grinded mostly on wknds… and they could be on point. But… I’ve tested and checked many times… the results are the same.
In essence, it seems that no matter how you ride the constellation, combat sites are seldom seeded on weekends and they just don’t respawn, while on weekdays, the chances of respawn within the same constellation do exist.
I have not brought this to forums but I’d like to know what other players have found and if there’s a casual DEV around, could perhaps clarify.
