thanks for the reply, but these were fully grown and then they just disappearedI've noticed with the lag that at times when it looks like you planted crops they don't always 'plant' even though the visual shows otherwise. After planting something that takes a while to grow I'll visit the hub and then come back to my island to see what didn't stick so I can replant.
It's annoying, but I haven't found any other way around it.
