Summary	0008273: CHANGED_TELEPORT is triggered on some border crossings
Description	When you walk or fly across a region border the changed() event is sometimes called with the CHANGED_TELEPORT bit in the parameter. This most often happens when you walk or fly across a region border going north to south or east to west. But on some border crossings in those directions changed() is not called with CHANGED_TELEPORT. So fly around until you find a border where this happens. Once you find a border with the problem it will consistently demonstrate the issue. I have never seen the bit set when crossing south to north or west to east. I'm not sure what the correct behavior is. I know that crossing a border is similar to teleporting to another region. Should this bit be set on any crossing? Or suppressed since a crossing doesn't feel like teleporting? HOWEVER, either way it should be consistent and not different depending on what direction you are crossing.
Steps To Reproduce	Put the following script in a prim, wear the prim as a HUD or attachment. Fly back and forth across several borders and look at the messages in chat.
Additional Information	//Put the following script in a prim, wear the prim as a HUD or attachment. //Fly back and forth across several borders and look at the messages in chat. //sometimes you will see the CHANGED_TELEPORT bit appearing on a border crossing //I think that bit should not be there on a border crossing default { state_entry() { llSay(0, "reset"); } changed(integer flag) { if (flag&CHANGED_REGION) llSay(0,"Changed Region"); if (flag&CHANGED_TELEPORT) llSay(0,"Changed Teleport"); } }
