Title. I had a theory about why the Ringing Deeps in particular would lag every few hours substantially.
Then I realized that it always went away within about 10 minutes of the Lurker summoning.
So I tested it. I stayed by the lever, and waited. Sure enough, the lever spawned, and general chat starts spamming “LAG.”
I did it 2 more times, and again, the levers would spawn, and the lag would start.
I do not know how it’s causing it, but 3 times tends to mean a pattern.
