Its kind of hard to use afk mob farms when you get kicked after 20 minutes of being afk. Honestly, I'm not really sure why there is an afk timer on this server being vanilla and all. I mean, I under stand the server restart every 3 hours, but the afk timer I do not.
I mean I guess it helps stop lag created by players who aren't playing, but unless they're afk over a massive 100+ passive mob farm, I can't see it creating that many problems.
To be fair, I'm no server expert. I don't run servers nor do I understand the exacts of how it works, all I really know is that the two things that cause notable lag are portals, and entities. The later of which, unless passive or nametagged, will de-spawn given some time.
So to sum things up, why is there a Afk timer? All it's doing is being an annoyance to anyone who tries to go afk over 20 minutes.
Thanks you for reading my rant.
