PA removed bug and now House of Horror it's impossible to complete again.
Everything is impossible to complete. The amount of griefers keep increasing. They attack you in the robot for red light, green light and they attack you in the house of horrors. There's really no way to beat it unless you luck out and find a good server.
Dear PA....
Events are meant for fun and to get the community together. Please, next time you make an event, please, please, PLEASE make sure there's no way people can grief.
