We just played a game witch techs and had a player playing masochist.
Every turn he added a ship to his tech without using it.
When he had about 12 ships on the tech he had his other 8 ships in the warp.
Of course he completed his tech here forcing himself to loose all ships to the warp.
But i managed to fix it with a zap and then win my turn gaining five colonies.
So he didnt make it and i guess the game was played legally.
But still i think masochist have a big advantage with techs, right?
