Let me say this though, I would worry more about getting all the perks that have very steep costs (like Slayer's large 7 AGI cost, and Tunnel Runner's massive 8 AGi cost), more than I would about getting a level 2 perk to stick. You could also acquire Animal Friend if you opt for 5 CHR when doing your first set of perks, then once you leave you can drop it back down to 1 like normal, and still have that perk. :D
Yeay, the glitch I found is still active *does the monkey* lol Bethesda probably never bothered to fix this because the cheat required to do this takes hours and hours and hours and hours, lol.
But I did hear that it's not working very well now.
Some people stated that things like Strong Back stopped working if you selected it before the character reset. But even though it's still on the list there's no Strong Back bonus. It could be that they do not have the right amount of strength after the reset. It's still working for me.
Also Action Boy/Girl (Never pick these if you intend to change gender) doesn't always seem to work. I've tested this and it does for me though. Also note that if you started as a woman and changed to a man you'd sometimes still be addressed as a woman, lol.
