I wrote a nifty fix for these lag / crash items. It's rolling out to all servers but it's been fixed on creative and survival as of right now. ;D
It will stop people from crashing others simply by being near them, and glitched players emailing Emily with data reset requests should be a thing of the past. As far as we know we basically fixed everything.
OMG THANK U! Wow- it was CRAZY earlier, I wasn't able to get on Creative for... what, 5 days? O.O Thanks again!
Well, yeah, that's true... I actually posted my comment BEFORE I got on Minetime. Right now, at 4:10 PM EST, I can't log on. Well, I can... The issue is LAG. I can't place signs, I can't... yeah! I can't get on for 5 minutes without being "timed out". This is probably temporary. But for now, a Creative restart, maybe...?
Unfortunately, there's really no way for us to fix players that were glitched prior to us releasing this plugin -- but I'm going to wipe all playerdata later today and that should fix your issue.
