C.Skills = new Hashtable();
                    byte SkillCount = BR.ReadByte();
                    for (byte i = 0; i < SkillCount; i++)
                    {
                        Game.Skill S = new NewestCOServer.Game.Skill();
                        S.ReadThis(BR);
         [COLOR="Red"]Line 922-->[/COLOR]   C.Skills.Add(S.ID, S);
                    }

Change that to
C.Skills = new Hashtable();
byte SkillCount = BR.ReadByte();
for (byte i = 0; i < SkillCount; i++)
{
Game.Skill S = new NewestCOServer.Game.Skill();
S.ReadThis(BR);
if (!C.Skills.Contains(S.ID)){
C.Skills.Add(S.ID, S);}
}

I use this source (Deckers) because it has stuff fixed already and people are getting tired of my posts so i dont want to annoy people anymore so i used his source because i dont know how to fix poison fog or poison star or anything for that matter
