Um, when creative was crashing a while ago players were able to break anyblock, I saw players griefing left&right, before I didnt have a mouse so i accidentally hit a brick and it dissappeared...meaning everyone could grief, I disconected..when I went back on the changes were permanent..
At the road at my plot it's griefed with lava and everything, I'll show some evidence tomorrow I need some sleep ;-;
I know, if a player has access to a plot either side of him/her they would select a point on one plot and a point on the other. They they could do .//set lava,water,tnt,sponge etc... Im not sure if this would work but it is a possible way that people were greifing.
Locking until resolved, if you have any sort of evidence related to this situation, please file a new thread :worm:
