Sorry if this was in the wrong area, but my question does pertain to a land. So we all know Orientation is a no push, no script, no rezz area, yet for the past few weeks when I go there, I am being pushed (quite far) by some griefers. How is this possible in such an area? And an even better question, how can I avoid it without having to sit on something, teleport out, or muting? Thanks for taking the time to read; look forward to your replies.
