Well i guess that ur server has a stronger protection of depmax and it doesn't let u go in.The pictures are taken at L2Vicious,depmax protection,etc,etc.I manage to go through.Try it a few times,press this attack all the time move ur char with the arrows and if u still don't get in,i can't help u.
The egg of the queen ant does not exist when queen ant is up.Maybe it's a bug for ur server only.
