I was doing ZDROP drop party for the second time, and suddenly Minecraft started lagging near the end of the party, so much I could barely open up the menu, next thing I see there are tons of creepers spawning...Is this some kind of trick?.. are we meant to leave before they all kill us,,,

it was a joke...mob-damage and creeper-explosion are denied in the region

It's meant to be a fun end to a drop party.

It's not a "trick"

Sorry, just got worried since I had alot of valuables in my inventory..at the first dparty there wasn't anything like that. <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>
