Yes, TA, I renamed the file and the game works fine ;)

Floods were about the only thing we were getting too (rarely - and usually in the sea!) with the ocassional plague. Someone once said they got an earthquake.

I wonder if it's hardcoded to certain game conditions, floods and plague seem to occur when things are going well and population high and I wonder if it is triggered by such things in order to cut down population etc.?
