Hey Robby,
Today I was booking my pet in the library when I started to run out of hh cash I decided to check how many tickets I had at the time so I go to the pay vault to see my amount. I don't know how exactly but I know I was using an auto clicker to help book faster and I guess it was still on? Anyways long story made short I ended up buying the zombie skin and halo at least 10 times each. I had 700 tickets ( or around it, I can't remember exactly) but now if you look at the linked image I have -11. Please help.
