It sometimes happens that while I'm busy building a wonder an AI civ builds it and I have no other wonders left to build...in these cases I usually keep building the already built wonder in order not to lose the hundreds of shields (and I ignore the warning messages or turn them off), and when a new wonder becomes available I switch to that new wonder to build it very quickly.
Would you see this as cheating?

"Let's play Good Crop, Bad Crop", said the one potato to the other, and so it was done. That year the harvest was good and the Kingdom of Oogklootia prospered. The next year however ninety percent of the population died in a famine.
But the farmer still wouldn't talk.
