Changing the condom chance is fairly simple. 1) Download the app qgen (quests generator) and use this to open the game. 2) Scroll down the locations and double click "Cum_Manage". 3) Scroll down the execute on visit box until you find a line that says "if sexcontra = 3:" followed by "temprand = rand(0,1000)". 4) This line is what controls the chance, if you edit the 1000 to be a higher number the chance of condom breaking DECREASES, if you change the 1000 to a smaller number the chance of condom breaking INCREASES. 5) Hit save then open your game as normal.That sounds reasonable. Do you happen to know how overriding works here? If I want a mod to make changes to some core concepts like chance of condom breaking?
Make sure not to accidentally delete or change anything else or you could end up breaking your game.
