PreventLooting - Failed to compile: 'HashSet<ulong>' does not contain a definition for 'Any' and the best extension method overload 'ParallelEnumerable.Any<PlayerNameID>(ParallelQuery<PlayerNameID>, Func<PlayerNameID, bool>)' requires a receiver of type 'System.Linq.ParallelQuery<ProtoBuf.PlayerNameID>' | Line: 624, Pos: 51

you need to change that line to

if (bprev.IsAuthed(player) && bprev.IsAuthed(player.userID)) return true;

or download this fixed version if you dont understand how to change it
