I was using the server with at least 5 stacks of emeralds in my inventory. I exited the server to go and do something. When I came back I only had 5 emeralds. I spent a long time trying to get them and i'm worried this might happen to other players.
If I had to guess, he would be talking about KivPvp. You can get tons of 'Emeralds' from that mini-game.
Did you check your player vault or your enderchest? You may have placed them there without thinking/forgot about it.
More detail on the problem? Did you lose it in the ended chest/ vault or did u place it in a public community chest?
I checked everything. I just had to leave minecraft for a minute. When I reopened minecraft they were gone. I was not in the warzone, just the kitpvp spawn.
It is hard to fix this issue due to people lying about these things. Please provide evidence with your issue.
