canceled research, after completion

Joined an FP game on day 2. Suprised to find that over a dozen researches had been completed,

but no buildings! Recruited some cruisers, bombers and tanks.

At day 3, ALL of the research was gone!

since this is an FP game, it might be an experiment giving AI free research?

or just another glitch?

game number is 5,481,932
