I am sorry that the event was negative for you. I realize that it can be very difficult to adjust to what usually amounts to total chaos. We want this to be fun for everyone and will do our best to avoid this type of thing in the future. I will try Friday, but holiday activities with my family come first this time of year. I'll post an update when I know more.
I just ended my group mining session. It was definitely a better one than my pasts attempts. I found two zombie dungeons touching each other, connected to an abandoned mineshaft! The dungeon chests had several name tags, music discs, and other goodies in them!
I think I ended up coming across that mineshaft when I was trying to find a way to the surface. Ended up having to dig my way up hehe
