If a property is on the sim border, bumping into a restriction barrier causes the person to be flung 256m to the other side of the sim instead of just bouncing them back.
For example, if I am walking through Sim A headed west and a plot in Sim B bordering Sim A is restricted, when I bump into the barrier, instead of being bounced back east 2m, I am flung 256m west to the other side of Sim B.
I have encountered this a number of times. The land owner has every right to restrict the land, but the punishment for bumping into the restriction should not be being flung 256m away from the infraction. It just needs to work properly and bounce the person back.
