Would have been a nice mosaic, but after doing the first three missions I find that the fourth no longer exists. So only parts 1, 2, 3, 5 and 6 are available. This has now ruined my mission scanner. The mosaic owner does not reply to PM. It would be better if all the missions were removed until the full mosaic is available again.
It's not as if I can pop over to Curacao every week to complete the mosaic.
A real shame!
Update. Owner contacted me before I left (had been away). The fourth mission had dropped into 'edit mode' for some reason and the owner resubmitted it. Fortunately, it only took Niantic 4 days to make it active again and I was able to complete the mosaic on my final morning in Curacao.
