I keep having infinite lag attacks for some reason (by 'infinite' I mean it doesn't stop until I leave the server). I'm usually able to see other people's chat when it happens and it fixes if I rejoin the server.
I finally caught it while in trace, so I'll attach the console.log. I turned trace off about 10 seconds after the lag started, and you can't see where I turned trace on because I edited it out - I had trace on for about 15 minutes so the file was too big to include everything. I still included a lot though.
