Disappearing corporations.

I run a country which was running doing very well yesterday.

Today I face MASSIVE unemployment.

For some reason, 13 CEO run corporations disappeared during the night.

According to the graph of number of corporations, they all vanished in the same month.

While I didn't look closely at them, they appeared to be running well yesterday. (No red triangles, >120% production)

What are the possible causes of this?

the lose of CEOs will cause unemployment, of coarse. Lack of supplies may be the source if you are a free player, but I nor others can assist any farther than this because we don't know where you are located. Also, dismantling your armies until you are of reasonable size will free up more workers for you.

The question was: What could cause the simultaneous disappearance of 13 corporations?

An earthquake perhaps?

Earthquakes, automatic closing because of there's too much Need of a working Group your Country cant supply, CEOs moving their Corps out because of high taxes/low welfare/low employments,......
As Brandon said above, say which world, which Country and we can have a look at it and maybe tell you more

As there where 13 Corps of CEOs dissapearing in one month i guess that there was a CEO that was unregistered and/or a CEO that moved Corps out, dont know that reason, Indexes are good, so I'd say just coincidence but can happen

Corporations doesn't survive their CEOs? I though Gamemaster Corporations took over.

dunno, maybe
