I've repeatedly had an issue with my Meeroo going beyond the range I set them to, especially while I'm away from them and it sets them to the low activity mode. When I set them at 2m and 5m I don't seem to have this issue as much, but at 10m and 20m they seem to go beyond the range set and then stop communicating with the stuff until I pick them up and place them back next to it. I built an enclosure that was 40m in diameter with lines marked on it to see how far they would go when this problem happens and each time they actually moved OUTSIDE the 40m mark, so they were floating outside the enclosure, usually appearing to be asleep. Typically the only way I know it's happened is when I get a message saying " Meeroo is hungry but does not appear to be near a food dish" or something similiar, or "Meeroo Home V0.76: has gone for a wander away from home.." and then they are no longer even listed as living in the stump.
