I started working on my quest after taking a while off, and now my water tiles aren't working as water (dark blue). I have upgraded the OS to Windows 10 since last editing so I don't know if the upgrade is part of it:

The tiles themselves are classified as water and all 4 quadrants are blue. I am not sure what is wrong, link is walking over the dark blue as if they are none and the shallow water (light blue) like they are still shallow.
