I think the problem was already tracked down in the other topic about this, linked earlier:
And also because of how the cooldown is saved: its not a permanent save and gets cleared in case the world with the beacon, or all servers in the case of patches, goes offline for whatever reason, or crashes, etc.
So, my hypothesis is that with servers crashing less lately, it became more obvious that the 24 hour cooldown was not working as intended, leading to the decreased footfall we’re seeing recently.
