Strange mysterious circles in the sea in IF

[Ondrej]

Hello IFC, today, I went to space because I felt like it as I have never done it before. I am still there now, but I encountered something really strange. A sort of two massive circles in the sea. One which is black and another with lines and dots which move occasionally.

Sorry, but can’t resize it. Please raise screen brightness to see.

Thanks for looking at this. Also, is this a sort of bug?
Many thanks all of you.

My first suggestion would be to clear the scenery cache.
Also, since you are viewing this through the exploitation of a bug, it is probable that you will see additional bugs because of this original bug.

I don’t think it’s that I cleared it this morning.
