Today (Sunday) at 15 PST we’ll be trying out a fix for the teleportation accidents that keep happening. In case something goes horribly wrong (not unheard of with teleporters) there will be a rollback. You can follow the progress on Twitter.
Seems to work fine, teleporting will now force your client to reload all chunks beforehand which is slower, but hey, at least you won’t die horribly. Kudos to Euske for researching and coming up with this workaround!
MCA will be down for a bit because we’re messing about with worldedit for the challenge. No, I don’t know if it’s still canceled, sorry. We will announce when it’s back open to the public here and on Twitter.
