Bug : Confirming one wants to retire, then leaving the game and returning while the prestige bonus selection is still active leads to all the tabs being unlocked on reload, with prestige management still open. I was able to dump a bunch of upgrades into Corpo background, run some Hack based money making schemes with my +7 bonus, then readjust the prestige benefits to something more realistic for a whole cycle. Presumably the same could be done for bulking up on Schmooze Intel and Tech Scrap right off the bat.
Confirming my selections reset the lifespan but not my money. I didn't do a full run to test to see what did and didn't reset.
