Just for those who might be short on prim or have leased places on other sims for their mossms, the updater calls all your mossms from the entire grid to you. They do rez beautifully and are easily relocated from the circle.

This is a good tip! Thank you for sharing it!

Another tip to go along with that one...
If you are short on prims you can take the updated Mossms to inventory as soon as they are rezzed without interrupting the rest of the update process.
