I've been breeding things in Black 2 lately and I've noticed the good ol' RNG isn't as random as it should be with abilities (at least, when circumstances are such that they should be a 50/50 draw, like when using Ditto). It seems like, at least for the first egg you try to hatch, the game seems to favor one ability over the other (subsequent eggs will be back to random chance, at least if you're continuing to breed the same things). I'm guessing this is a glitch of some sort, but I'm surprised I've never seen it mentioned before. At least it doesn't hurt anything (kinda helpful when the game is "stuck" on an ability you want, not so much when it's the ability you don't want).

Has anyone else ever noticed this?
