Is this unusual, as this has never happened before when I played my game on my main puter I never had the algae after playing for at least a week and only had it happen after the dam is completed. Not even gone there yet.
This is the history of my village from when I opened it:
Started off as normal. I had my first event fish for the birds and since my villagers needed food to tast the fish, My villagers got 250 food, My next event was soupy fog and when the fog lefted The villagers found a (can't remember the spelling) something on researching and my villagers gain 1500 tech points. So I was able to buy farming after earningthe rest of the tech points in one hour.
The next strange thing was the coconut trees as expected had 1500 coconuts to harvest. Yet my farmer did not bother to harvest the coconuts, but instead go fishing. After catching so many fish he decided to harest the coconuts. Then there were 1482 coconuts, which I expected. Then my farmer decides to fish again and I check the coconut trees and was surprised to find there was 1500 coconuts left to harvest again and I wonder where the extra coconuts came from.
After playing for 3 to 4 hours my farmer went back to harvesting the coconuts which by now had 1494 which ment he harvested another 6 coconuts. Then I noticed the green algae in the ocean. So I wondered if I had my game on hard and checked the options and it was on easy and slow, This happened yesterday.

PS I took the pic tonight as I had no time to take it last night.
