Hello, your friendly neighborhood tech guy here.
Even though I'm not your tech guy.
Or anybody's for that matter.
But I'm a guy. Who knows tech stuff.
Anyways; solution, now to most people I'm gonna sound stupid. But 1ce, I told you from the start 4GB of RAM wasn't enough.
I was clearly right.
8GB.
"It only happens when a lot of people are on"
It could very easily be it's people having a hard time downloading the chunks because of our RAM.
Also see your bandwidth and internet speeds.
Good day.
