Whilst playing on the Minecraft server yesterday I was in the middle of raiding when all of a sudden I am being hit by a purely invisible person. I lost a lot of armour and was kind of annoyed. Just today I was raiding another faction and the same thing happened this time I couldn't play on because id just lost iron armour to people with stone pickaxes. I don't know what what's up whether it is plugins or Minecraft but its really making raiding hard. If there is any suggestions on how to fix this problem I would really like some help. Thanks.
