The issue on the sims in question is self-replicating prim that roll and bounce along the roadway running through this part of mainland. They're invisible but all over at least 11 sims. I filed multiple ARs, as well as a ticket, and was told the same thing by LL: that I should 'file ARs' so that the 'relevant group' would see it and take action.
Yes, the scripted objects are invisible. If I turn off transparent, I don't see them. They do, however, take up prim resources, bump me if they hit me while standing, and are a nuisance.
