Ocean visible when digging out filled ocean area

Describe the issue
When an ocean tile is filled in, you can later dig it out again if is surrounded by land. The water object will still be there.

To Reproduce
Steps to reproduce the behavior:

1. Fill in ocean and surrounding tiles
2. Dig out an area that was ocean but is now surrounded by land.
3. Dug out area shows water still

Expected behavior
Ocean should somehow propagate from outside the island and not be static.

Additional context

• Game version: 0.2.12

Attachments
Save file attached.

G6.save

After reloading my save the ocean bit no longer appears.

Thanks for reporting this. Unfortunately ocean only recomputes after load, we need to make this more dynamic.

For now, save&load should fix this.

At least in my case, save&load does not help.

This occurred yesterday. I loaded an autosave (did not manually save) just a few minutes ago and took that screenshot.
Additional info:

• Game is up to date as of now (0.3.8)
• Area is actually "normal ground" and not landfill expansion (note the straight-edge-expansion and natural shoreline)

This still occurs version 0.3.11f. Tried reloading and did not fix the issue. This is mined terrain, not filled in ocean.
