random number generators are seeded and unable to be completely random , saying that they can duplicate its effects as good as you need especially for something as simple as a d20 roll, as thats part of the main game engine and some of the most important code in the game given the amount of fights the seed number generator should be extremly good, so i doubt its that, when i want anything over a 1 on a d20 i should get in 19/20 attempts, to fail twice or more ticks me off
