I placed some moths and other insects in a garden I'm building hoping they would move about like normal, but they just hover there in place not moving an inch. I found the landing marker for the moths as well, but it doesn't seem to do anything. I've tried looking around for answers to no avail. I'm sure there's something obvious that I'm missing, but I can't figure it out for the life of me. How do I get these bugs to move!?
