so we were doing a simple citadel run. One team mate (wedmoretw) was down, and the other one (aznlife) had just lagged into some spikes by accident. Our third member (Kazuki) was on his way down to revive the downed member to the south, and I was going to rev the one who lagged into the spikes. As i stepped on the group button, the other downed member teleported in and the mob spawned, locking poor ol Kazuki outside the gate.

we fixed it by Kaz forcing a disconnect then rejoining the party, but wasted 10 energy so... yeah
