I found what I think is a bug. And I know I should probably go to the "JIRA" instead but who can figure out how to navigate that things?
Ok, so I was testing this "unsitter" I'm making. Basically I say "unsit.self" and it makes me stand up. (The object is attached to me, by the way) And it seemed to be working for, expect for when I sat in certain places. And I could figure out why it stopped working on in those certain places. Then (I think) I figured it out. I was sitting on a megaprim. A megaprim larger than 20 meters, which is the normal chat distance. So then I tried shouting "unsit.self", and it worked. So it seems like sitting on a megaprim somehow makes it so you're...I don't know, too far away from yourself for your attachments to hear what you say? Anyone else experienced this?
