We'll make sure we check again in the morning. We should be better at handling this type of griefing.
Punishment aside, I'm curious - do you think there are any content changes we can make to stop this type of thing within Castle Wars, but without negatively affecting the gameplay?
EDIT: I've had a few replies mention limiting barricades. It sounds good in theory, but I'd need to learn about the competitive Castle Wars community and how it'd impact their games before we hurry into something like that.
