Invisible Mangrove Propagule

Whenever I try to put a Mangrove Propagule inside a flowerpot it is invisible. The Mangrove Propagule is in the flowerpot though... you just can't see it. This is a problem for me because I really love building and I love to decorate with plants. Other than that little bug I am really enjoying the Wild Update!
