Ivys plants are taking? over. When I start from my starting point I go in the Glassroom in the gardens I immediatley am in ivy and can not manuever out of it. There is only one other room to go to and it has a electric gate that I can not pass through because I can not find where to use the crypto gun. I have tried repeatedly tapping X when standing in the vines hitting X, and with the battarangs nothing gives please any hints will be appreciated.
