What causes Purge

How does purge work? Does the meter increases with time or kills or both?

You can read about purge here.

But it doesn’t tell much. We still don’t get to understand the why and the when a purge will happen.

What I learned about purge by playing though, the more I play the more the purge meter will fill, so for the last few days I went online only for resetting the decay to my base then I logged off. To my surprise, I just checked a few minutes ago, the purge meter is now below 50%. WTH.

It’s kinda like the game is telling me to quit playing or else my base will get destroyed, and to be honest I have lost my interest playing Conan Exiles for the last few days.
