I applied the patch for Lockdown, then entered the Iron Serpent gate tonight. I forgot to choose start a party, so I joined someone instead, in depth 9, a deconstruction zone. I went solo immediately.
Then I walked over and killed a bunch of gremlins and mecha knights, grabbed a crystal, and opened the first gate there. I killed the bombers and only two menders were left in that room. I cornered one mender and killed it in a corner with sword. Right as the mender dropped a huge number of "Stun" effect pops up and I died. I was nearly at full HP before that.
There's no other enemies around, only two menders of which one I killed. My connection's fine before and after. I submitted a request but no GM came. Eventually the game kicked me.
Gimme back my 10 mist.
In the mean time I suggest people shoot menders.
A GM appeared after I started another dive. He said my JVM is not the latest version - true enough, and Java 7 does have performance improvements in it. I will install JDK7 (I am a programmer too) later today. My second dive turned out fine - no lag, and no more death by menders.
But I stand by the fact that I've experienced no lag before and after my death by stun, and that there were nothing but 2 menders (one already killed) around the area.
So even if the network did somehow choked for a while at that point, there were still nothing to deal damage to me - except that single mender, which should remember its oath to do no violence.
Or, there's something strange happening after I went solo right after joining a game.
