GirTheRobot has won the Easter Umbrella October Raffle! Next up: Slyme Costume!
Both Horizontal & Vertical rings become dislodged and lay on the ground daily. I first noticed in someones realm a few weeks ago and now it is happening in at least one of my realms/rooms daily. I walk in to find the ring laying on the ground and have to build scaffold to put it back in its place.
For sure at least once per day in my kitchen on the left side in Buy The Farm.
I place my lowest vertical ring at lvl 4 and the next ring 9 lvls above that. It is always the 2nd ring that becomes dislodged in the previously mentioned room. This is how I place all of my rings and the others (eight other rooms) stay where I have placed them.
Another realm was Koekenbak pixel vend room near the entrance of Koeks rentals. This ring was a horizontal but has been removed.
